A study of aerosol variations in the Central Pacific Ocean was conducted utilizing NOAA-9 AVHRR data and concurrent shipboard measurements from the NOAA RV OCEANOGRAPHER during the RITS-88 cruise. The transect was conducted 7 April to 5 May 1988 along longitude 170 deg W from latitude 50 deg N to 12 deg S. Aerosol physiochemistry measurements were provided every 1 deg of latitude. Satellite observations of optical depth, Aerosol Particle Size Index s sub 12, channel 1 0.63 microns, and channel 3 3.7 microns low cloud reflectances were analysed. These parameters were evaluated during several naturally occurring events, foremost of which were the Gobi desert dust storms and the eruption of Kilauea volcano. By comparing shipboard and satellite data, satellite retrieval techniques were verified, shipboard measurements were expanded to a regional scale, and the relationship between solar reflectance and the microphysical properties of clouds were verified.
