Data from the Microwave Profiling Radiometer and the Radar Wind Profiler are combined and processed through algorithms that determine the presence and liquid water content of radiative-based fog. Using sunrise/sunset information, liquid water content, temperature, dewpoint, and wind profiles, a one-hour nowcast of fog trend is provided. This trend is updated every 15 minutes.
