The principal activity under this grant was the DYCOMS-II field experiment, and the data analyses and reporting that followed. The field experiment yielded unique data. Results have been reported in a number of publications and student theses and dissertations. Additional journal articles are pending publication andor submission. The main finding from the field observations is the ubiquity of drizzle in marine stratocumulus even when cloud thickness is as little as 250 m. Diagnosis of this drizzle became possible through the use of the Wyoming Cloud Radar on the NSFNCAR C-130 research aircraft. In addition, the drizzle provided a suitable target for velocity measurements, so that we were able to obtain the first ever two-dimensional depictions of circulations within the marine boundary layer.
