Horizontal Variability of the Marine Boundary Layer Structure Upwind of San Nicolas Island during FIRE (First ISCCP (International Satellite Cloud Climatology Project) Regional Experiment), 1987

摘要

The Naval Ocean Systems Center airborne platform was used to determine the representativeness of island-based measurements to upwind open ocean conditions. Large differences existed in the meteorological profiles between the open ocean conditions and those taken near the island. A higher concentration of surface-based aerosols existed at the island. The vertical optical depths at the island were not significantly affected by this surface-based aerosol layer. Sea surface and cloud top temperatures near the island did not in general represent those observed upwind.
