Boundary Layer Thermodynamic and Wind Observations for Improved Fog and Marine Layer Modeling and Forecasting

We present continuous boundary layer thermodynamic and liquid profiles derived from microwave radiometer observations at San Francisco and other locations. Close correlation is found between these data and fog and marine layer formation and dissipation. Boundary layer winds also play an important role in fog and marine layer processes. The current status of boundary layer thermodynamic and wind observation and use to improve fog and marine layer modeling and forecasting will be discussed.
