Activity during the 1992 calendar year centered around the ASTEX project in the Azores and what has been, essentially, a small follow-up experiment conducted off of the Washington-Oregon coast, at least partially in conjunction with a series of test flights by the newly outfitted NRL blimp. The main experiment, conducted during ASTEX, had several objectives: (1) evaluate data for the occurrence of significant relationships between DMS, SO(2) SO equal 4 and CCN concentrations, (2) evaluate the strength of the relationship between boundary layer CCN concentration and cloud drop concentration in capping stratocumulus decks, (3) investigate the evolution of the particle size distribution in the boundary layer and (4) assess the effect of ship-induced aerosol flux on cloud dynamics and chemistry. The west coast experiment concentrated on only the fourth objective of the ASTEX study. A review of data reliability has been undertaken, and some preliminary data analysis as well.
