Linkage of anthropogenic aerosol to clouds and climate. Progress report No. 3

During the first year of this project equipment was built to obtain direct droplet measurement data from a mobile platform in fog (or mountain impacted stratum) and to characterize CCN according to particle volatility (thermal processing). Since the start date, July 15, 1990, was during the California stratus season and it was necessary to complete the construction of equipment and allow time before a field project it was not possible to begin field work until the summer of 1991. This report discusses surface measurements made in 1991 and 1992 as well as the SEAHUNT (Shiptrail Evolution Above High Updraft Naval Targets) Project and the ASTEX (Atlantic Stratocumulus Transition Experiment) Project
