The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH. Twenty one 1.6 cm inner diameter stainless steel tubes extending into the heated portion of the mast were connected to downstream aerosol instrumentation with either conductive silicon tubing or stainless steel tubing for analysis of organic aerosol.\n\nDMPS (datasets denoted by _aerosol_sizedist_dmps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to a tandem DMPS system that measured particle size distributions in the range of 0.020 to 0.8 micrometers Stokes diameter. The tandem DMPS consists of an \"Aitken\" DMPS (0.020 to 0.2 um) and an \"Accumulation\" DMPS (0.2 to 0.8 um). The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nAPS (datasets denoted by _aerosol_sizedist_aps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to an APS that measured particle size distributions in the range of 0.96 to 10 micrometers Stokes diameter. The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry.

The field study will take place in the tropical North Atlantic east of Barbados and investigate cloud and air-sea interaction processes with the goal of advancing understanding and prediction of U.S. weather and climate. ATOMIC is the U.S. complement to the European field campaign called EUREC4A. This collaborative effort involves a unique combination of ships, piloted and remotely-controlled aircraft, and remotely-controlled ocean vehicles to characterize ocean and atmospheric properties. A suite of instruments will be deployed from NOAA's research ship Ronald H. Brown and WP-3D Orion \"Hurricane Hunter\" aircraft, and on land.\n\nThe focus area of ATOMIC is in the heart of the trade winds and representative of other regions across the global ocean with shallow convective clouds. Some of the Earth's largest ocean eddies (circular currents) also shed into this region from the Amazon and Orinoco Rivers.

The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH. Twenty one 1.6 cm inner diameter stainless steel tubes extending into the heated portion of the mast were connected to downstream aerosol instrumentation with either conductive silicon tubing or stainless steel tubing for analysis of organic aerosol.\n\nDMPS (datasets denoted by _aerosol_sizedist_dmps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to a tandem DMPS system that measured particle size distributions in the range of 0.020 to 0.8 micrometers Stokes diameter. The tandem DMPS consists of an \"Aitken\" DMPS (0.020 to 0.2 um) and an \"Accumulation\" DMPS (0.2 to 0.8 um).

The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel.

Finally, the regridded distributions were cleaned to eliminate values at the larger sizes from the APS where \"phantom\" counts resulted in a spurious coarse mode in the surface and volume distributions.\n\nAll datasets include number size distributions (normalized and non-normalized) as well as the higher moments for each: surface area and volume.\n\nAdditional datasets may be included for a give project that include:\n - ambient (_ambient_): includes size distributions shifted to ambient RH using gRH factors\n - filter (_filter_): includes size distributions where additional cleaning was performed for periods of unstable CN concentrations\n\ncdm_data_type = Trajectory\nVARIABLES:\ntime (Datetime UTC, seconds since 1970-01-01T00:00:00Z)\n...

The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH.

The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel.

The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH. Twenty one 1.6 cm inner diameter stainless steel tubes extending into the heated portion of the mast were connected to downstream aerosol instrumentation with either conductive silicon tubing or stainless steel tubing for analysis of organic aerosol.\n\nDMPS (datasets denoted by _aerosol_sizedist_dmps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to a tandem DMPS system that measured particle size distributions in the range of 0.020 to 0.8 micrometers Stokes diameter. The tandem DMPS consists of an \"Aitken\" DMPS (0.020 to 0.2 um) and an \"Accumulation\" DMPS (0.2 to 0.8 um). The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nAPS (datasets denoted by _aerosol_sizedist_aps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to an APS that measured particle size distributions in the range of 0.96 to 10 micrometers Stokes diameter. The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel.

Finally, the regridded distributions were cleaned to eliminate values at the larger sizes from the APS where \"phantom\" counts resulted in a spurious coarse mode in the surface and volume distributions.\n\nAll datasets include number size distributions (normalized and non-normalized) as well as the higher moments for each: surface area and volume.\n\nAdditional datasets may be included for a give project that include:\n - ambient (_ambient_): includes size distributions shifted to ambient RH using gRH factors\n - filter (_filter_): includes size distributions where additional cleaning was performed for periods of unstable CN concentrations\n\ncdm_data_type = Trajectory\nVARIABLES:\ntime (Datetime UTC, seconds since 1970-01-01T00:00:00Z)\n...

The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH.

The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet.

PMEL Size Distributions\n    \n    Aerosol inlet:\nAmbient aerosol particles were sampled at 18 m above sea level through a heated mast. The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH. Twenty one 1.6 cm inner diameter stainless steel tubes extending into the heated portion of the mast were connected to downstream aerosol instrumentation with either conductive silicon tubing or stainless steel tubing for analysis of organic aerosol.\n\nDMPS (datasets denoted by _aerosol_sizedist_dmps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to a tandem DMPS system that measured particle size distributions in the range of 0.020 to 0.8 micrometers Stokes diameter. The tandem DMPS consists of an \"Aitken\" DMPS (0.020 to 0.2 um) and an \"Accumulation\" DMPS (0.2 to 0.8 um).

The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel.

The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH. Twenty one 1.6 cm inner diameter stainless steel tubes extending into the heated portion of the mast were connected to downstream aerosol instrumentation with either conductive silicon tubing or stainless steel tubing for analysis of organic aerosol.\n\nDMPS (datasets denoted by _aerosol_sizedist_dmps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to a tandem DMPS system that measured particle size distributions in the range of 0.020 to 0.8 micrometers Stokes diameter. The tandem DMPS consists of an \"Aitken\" DMPS (0.020 to 0.2 um) and an \"Accumulation\" DMPS (0.2 to 0.8 um).

The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel.

Finally, the regridded distributions were cleaned to eliminate values at the larger sizes from the APS where \"phantom\" counts resulted in a spurious coarse mode in the surface and volume distributions.\n\nAll datasets include number size distributions (normalized and non-normalized) as well as the higher moments for each: surface area and volume.\n\nAdditional datasets may be included for a give project that include:\n - ambient (_ambient_): includes size distributions shifted to ambient RH using gRH factors\n - filter (_filter_): includes size distributions where additional cleaning was performed for periods of unstable CN concentrations\n\ncdm_data_type = Trajectory\nVARIABLES:\ntime (Datetime UTC, seconds since 1970-01-01T00:00:00Z)\n...

The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH. Twenty one 1.6 cm inner diameter stainless steel tubes extending into the heated portion of the mast were connected to downstream aerosol instrumentation with either conductive silicon tubing or stainless steel tubing for analysis of organic aerosol.\n\nDMPS (datasets denoted by _aerosol_sizedist_dmps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to a tandem DMPS system that measured particle size distributions in the range of 0.020 to 0.8 micrometers Stokes diameter. The tandem DMPS consists of an \"Aitken\" DMPS (0.020 to 0.2 um) and an \"Accumulation\" DMPS (0.2 to 0.8 um). The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nAPS (datasets denoted by _aerosol_sizedist_aps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to an APS that measured particle size distributions in the range of 0.96 to 10 micrometers Stokes diameter. The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel. Each combined distribution was regridded onto a common set of diameters. Finally, the regridded distributions were cleaned to eliminate values at the larger sizes from the APS where \"phantom\" counts resulted in a spurious coarse mode in the surface and volume distributions.\n\nAll datasets include number size distributions (normalized and non-normalized) as well as the higher moments for each: surface area and volume.\n\nAdditional datasets may be included for a give project that include:\n - ambient (_ambient_): includes size distributions shifted to ambient RH using gRH factors\n - filter (_filter_): includes size distributions where additional cleaning was performed for periods of unstable CN concentrations\n\ncdm_data_type = Trajectory\nVARIABLES:\ntime (Datetime UTC, seconds since 1970-01-01T00:00:00Z)\n...

The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH. Twenty one 1.6 cm inner diameter stainless steel tubes extending into the heated portion of the mast were connected to downstream aerosol instrumentation with either conductive silicon tubing or stainless steel tubing for analysis of organic aerosol.\n\nDMPS (datasets denoted by _aerosol_sizedist_dmps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to a tandem DMPS system that measured particle size distributions in the range of 0.020 to 0.8 micrometers Stokes diameter. The tandem DMPS consists of an \"Aitken\" DMPS (0.020 to 0.2 um) and an \"Accumulation\" DMPS (0.2 to 0.8 um).

The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel.

The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH.

The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet. The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nMerged (datasets denoted by _aerosol_sizedist):\nThese datasets include particle size distributions in the diameter range of 0.005 to 10 micrometers Stokes diameter. The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel. Each combined distribution was regridded onto a common set of diameters. Finally, the regridded distributions were cleaned to eliminate values at the larger sizes from the APS where \"phantom\" counts resulted in a spurious coarse mode in the surface and volume distributions.\n\nAll datasets include number size distributions (normalized and non-normalized) as well as the higher moments for each: surface area and volume.\n\nAdditional datasets may be included for a give project that include:\n - ambient (_ambient_): includes size distributions shifted to ambient RH using gRH factors\n - filter (_filter_): includes size distributions where additional cleaning was performed for periods of unstable CN concentrations\n\ncdm_data_type = Trajectory\nVARIABLES:\ntime (Datetime UTC, seconds since 1970-01-01T00:00:00Z)\n...

The mast extended 5 m above and forward of the aerosol measurement container. The inlet was a rotating cone-shaped nozzle that was automatically positioned into the relative wind to maintain nominally isokinetic flow and minimize the loss of supermicrometer particles. Air entered the inlet through a 5 cm diameter hole, passed through a 7 degree expansion cone, and then into the 20 cm inner diameter sampling mast. The flow through the mast was 1 m3 min-1. The transmission efficiency of the inlet for particles with aerodynamic diameters less than 6.5 um (the largest size tested) is greater than 95% [Bates et al., 2002].\n\nThe bottom 1.5 m of the mast were heated to establish a stable reference relative humidity (RH) for the sample air controlled to the indicated target sample RH. Twenty one 1.6 cm inner diameter stainless steel tubes extending into the heated portion of the mast were connected to downstream aerosol instrumentation with either conductive silicon tubing or stainless steel tubing for analysis of organic aerosol.\n\nDMPS (datasets denoted by _aerosol_sizedist_dmps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to a tandem DMPS system that measured particle size distributions in the range of 0.020 to 0.8 micrometers Stokes diameter. The tandem DMPS consists of an \"Aitken\" DMPS (0.020 to 0.2 um) and an \"Accumulation\" DMPS (0.2 to 0.8 um). The distributions have been cleaned of all data from times of instrument malfunction or calibration.\n\nAPS (datasets denoted by _aerosol_sizedist_aps_):\nOne of the twenty one 1.6 cm diameter tubes was used to supply ambient air to an APS that measured particle size distributions in the range of 0.96 to 10 micrometers Stokes diameter. The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet.

The APS diameters are aerodynamic and have not been corrected to Stokes diameter via calculation or estimates of particle density. The APS data larger than 10 micrometers are not useful due to significant particle losses in the inlets including the ship's sampling mast, distribution tubing and APS inlet.

The distributions are a combination of DMPS and APS size distribution data where the APS diameters have been converted to Stokes diameters using densities calculated from measured chemistry. The diameter channels in the overlap region were chosen in the following manner: the last DMPS channel was discarded and, after converting to Stokes diameters, the first APS diameter channel that was larger than the last valid DMPS channel was chosen as the first APS channel.
