AB: A shallow (approximately 100m), strongly stable boundary layer exists over the Gulf of Maine at all times during warm offshore flow. This layer inhibits vertical exchange of chemical species. The wind direction in the boundary layer is usually about 30 degrees different than just above it. This structure strongly affects the transport, processing, and fate of gas-phase and aerosol species emitted from the continent. This presentation will combine micrometeorological and sounding measurements from the NOAA Research Vessel Ronald H. Brown, buoy and surface measurements, profiler measurements, chemical and aerosol measurements from Brown and surface sites, and model results to describe the boundary layer structure and its implications for analysis of data from the Brown and aircraft during ICARTT.
