| attribute | NC_GLOBAL | comment | String | Calibration of the sunphotometers is based on Langley plots derived from measurements at Mauna Loa. The relative air mass, mr, was calculated using Kasten's formula. The total measured optical depth was used to calculate the aerosol optical depth by subtracting Rayleigh and ozone extinction, i.e., AOD = TotalOD - OD,Rayleigh - OD,ozone where OD, Rayleigh = P/Po x 0.00877l-4.05 + d(l) and P = the atmospheric pressure during the observation, Po is standard atmospheric pressure (1013.25 mb), and d(l) is a time-dependent minor correction for a shift in the filter l. OD,ozone = 0.01 at 500 nm and negligible at all other wavelengths. The 380 nm channel displayed a severe drift after DOY 338. Therefore, these data have been removed from the record. |

| attribute | NC_GLOBAL | summary | String | 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 Pacific Marine Environmental Laboratory (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). |
