AB: The DYCOMS-II (Stevens et al., 2003) field program provided extensive in situ aircraft and remote sensing observations for study of the physics and dynamics of nocturnal marine stratocumulus. GOES multispectral satellite datasets collected during the DYCOMS-II project have been utilized to study the variability of cloud microphysical characteristics associated with cloud layer structure, formation of drizzle and the influence of aerosol. While the GOES Imager data have limited spectral bands and spatial resolution in the infrared region, the advantage of high temporal resolution allows analysis of cloud layer evolution due to cloud microphysical processes, radiative flux and aerosol-droplet interactions at the specific times and locations of aircraft measurements. Measurements from the DYCOMS-II project aircraft are presented with remote sensing retrievals for case studies of nighttime stratus in the marine layer region offshore southern California. Mesoscale model derived boundary layer parameters are also applied to aid the analysis.
