Abstract:

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, SO2 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.
