A study of aerosol variations in the Central Pacific was conducting utilizing NOAA-9 AVHRR data and concurrent shipboard measurements from the NOAA R/V OCEANOGRPAHER during the RITS-88 cruise. The transect was conducted 7 April to 5 May 1988 along longitude 170 degrees W from latitude 50 degrees N to 12 degrees S. Aerosol physiochemistry measurements were provided every 1 degree of latitude. Satellite observations of optical depth, Aerosol Particle Size Index (S12), channel 1 (0.63 um), and channel 3 (3.7 um) low cloud reflectances were analyzed. There 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 was verified.
