For the times when the SCS system was not working, the heading was taken from the PMEL GPS course. The GPS course and the gyro heading usually agreed within several degrees as long as the ship was moving forward through the water at speeds above 5 knots. The ship's speed (knots) was taken from the PMEL GPS system. Both the speed and heading were averaged from the one minute data to make the 30 minute averages. The speed was averaged directly, the heading was separated into N and E components by taking the sin and cos respectively of the heading. After averaging the N and E components into 30 minute bins, the heading was recalculated using a 4 quadrant arctangent function. Atmospheric Temperature and Humidity: Air temperature and humidity were measured with the ship's RM Young sensor. The sensor was enclosed in an RM Young radiation shield. The data were averaged into 30 minute bins. Barometric Pressure: Barometric pressure was measured with the PMEL Qualimetrics sensor. The data were corrected using a linear regression with the ship's barometer and averaged into 30 minute values. Insolation (sunlight): Total solar radiation was measured with an Eppley Black and White Pyranometer (horizontal surface receiver -180, model 8-48, serial number 12946) and an Epply precision pyranometer (horizontal surface receiver - 180 (twin hemispheres), model PSP, serial number 133035F3) that were mounted on the top of AeroVan. Both instruments were calibrated by The Epply Laboratory on October 11, 1994. There were times when the sampling mast shaded the sensor. Most of these times occurred for about a 30 minute period in the afternoon. (When the ship was traveling South, the mast was West of the sensor). There were also times when the ship's mast shaded the sensor. These bad data due to shading have not been edited out of the 30 minute data record. The data reported here are 30 minute averages of the Eppley 8-48 (SN 12946) in watts per square meter. Any 30 minute period without valid data is marked with a -99. Winds: Wind speed and direction were measured with the PMEL Qualimetrics anemometer and the Ship's RM Young anemometer. The PMEL anemometer was mounted above the top of the rain/seaspray shelter at the top of the aerosol/gas sampling mast. The location of the PMEL anemometer was chosen primarily to select the times when the sampling mast was in the 'clean' sector, not being influenced by ship pollution. The ship's RM Young anemometer was located on the starboard side of the ship's mast, 33 meters above the water. The PMEL anemometer and ship anemometer were calibrated in the PMEL wind tunnel in July and October 1995, respectively. The data from the PMEL anemometer were recorded on the PMEL data logger as one minute averages. The data from the ship's RM Young anemometer were recorded on the ship's SCS data system as one minute averages. The final 30 min average data are reported in 6 columns: RelWindS, RelWindD, WindS, WindD, WindU, and WindV Relative wind speed (RelWindS) is the 30 minute average of the wind speed (in m/s) relative to the ship. The relative wind direction (Rel WD) is the 30 minute average of the wind direction relative to the bow of the ship (0 degrees, wind is dead ahead; +90, wind is from the starboard beam; -90, wind is from the port beam). Because the relative wind information is used primarily to determine local ship pollution episodes for air sampling, the PMEL anemometer was used exclusively for the reported relative wind. True wind speed (WindS) is the 30 minute average of the true wind speed in m/s. True wind direction (True WD) is the 30 minute average wind direction in compass degrees. The PMEL anemometer was located closer to the superstructure of the ship and the wind that it measured was more distorted than that measured by the ship's RM Young anemometer. Thus, the RM Young anemometer was used to derive the true wind speed and direction. During the few times when the SCS system was not working, the PMEL wind data were used. WindU is the true wind east-west component, wind from the east to the west is positive. WindV is the true wind north-south component, wind from the south to the north is positive The ship's gyro compass input was used to correct the relative wind to true wind. The wind vector was separated into North and East components and the ship's velocity vector components (as determined from the GPS record) were subtracted to find the true North and true East components of the wind. These components and the resulting (computed) speed and direction at one minute intervals were plotted. A few outliners were eliminated and the resulting data were reduced into 30 minute averages. The averaged North and East components were then used to calculate the 30 minute average wind speed and direction. Ozone: Two ozone uv analyzers were used, a Dasibi 1008 AH ,and a TECO 49. Both analyzers were calibrated to a NIST traceable analyzer at the NOAA-CMDL lab prior to the project. One minute averages of the output of each analyzer were recorded on the PMEL data system and plots were made of the raw data. A small portion of the data was deleted (consisting mostly of times that the inlet air was passed through a zero filter - usually when the relative wind was well behind the beam of the ship). After the raw data was cleaned, the calibration function from CMDL (offset and slope) was applied, and 30-minute averages were created. The 30-minute average from each instrument was then averaged together to create the final data. Total Particle Number (UFCN): The total number of particles with diameters 3nm were measured with a TSI 3025 UFCN at the base of the aerosol sampling mast. Missing and polluted data values have been replaced by -99. Units are particles per cubic centimeter averaged over the 30 min Rainfall Rate: The rainfall rate was measured with a Scientific Technology Inc. ORG-100 Optical Precipitation Intensity Sensor. The instrument was mounted on the railing of Aero van and was used along with wind direction, wind speed and CN to control the aerosol chemistry pumps. The dynamic range of the sensor is 0.5 to 1600 mm/h. Spikes in the signal are often associated with sea spray. The 30 minute averaged data include all data points. The data are reported in units of mm/hr. (Note: since the data are 30 minute averages, summing all 48 points for one day and dividing by two will give total precipitation in mm for that day.) Aerosol light scattering: ScatBlue, ScatGreen, ScatRed are the 60-minute averages of the total aerosol light scattering as measured by the PMEL TSI 3-wavelength (450,550,700nm) nephelometer. The instrument was calibrated on the cruise using CO2. Two impactors were placed upstream of the nephelometer. One had a nominal size cut of 10 um and the other of 1 um (at 55% RH). A valve was switched every 15 minutes by the data logger so that either light scattering of the total aerosol or of the submicron aerosol light scattering was measured. Submicron aerosol light scattering data are in the columns SubSctB, SubSctG, SubSctR. All light scattering is given in units of Mm-1, inverse megameters (1 Mm-1 = 1E-6 m-1). Missing and polluted data values have been replaced by -99. Seawater temperature and salinity: Seawater temperature and salinity were measured with the ship's thermosalinograph (Seabird SBE-21 serial number 843) and recorded on the ship's SCS system. The instrument was calibrated by the NW regional Calibration Center on 10/11/95 just before the cruise. The instantaneous one-minute data set from the ship was very clean and required very little editing. The data were averaged into 30 minute bins. Temperatures are reported in degrees C. Salinity data are in practical salinity units (psu).

attribute	NC_GLOBAL	summary	String	Pacific Marine Environmental Laboratory (PMEL) Atmospheric Chemistry ACE-1 Aerosol Main Data - 1 min data. The Southern Hemisphere Marine Aerosol Characterization Experiment (ACE-1) was the first of a series of IGAC experiments designed to quantify the chemical, physical, and meteorological processes controlling the evolution and properties of the atmospheric aerosol relevant to radiative forcing and climate. The PMEL-Joint Institue for the Study of Atmoshere and Ocean (JISAO) Atmospheric Chemistry Group conducted gas and aerosol measurements aboard the NOAA ship Discoverer from Seattle (11 October 1995) to Hobart (10 November 1995) and during the ACE-1 intensive south and west of Tasmania (15 November - 14 December, 1995).
