The assimilation of MODIS temperature and water vapor profiles into a mesoscale analysis system.  B.T. ZAVODSKY (1), S.M. LAZARUS (1), P.F. BLOTTMAN (2), and D.W. SHARP (2).  (1) Florida Institute of Technology, Melbourne, FL 32901, (2) NOAA, National Weather Service, Melbourne, FL 32901.  The Florida peninsula is unique.  The domain the coupled ARPS model and its analysis component, the ARPS Data Analysis System (ADAS), are run is dominated by the surrounding water, but data is sparse in these regions.  The off-shore analyses converge to the background field due to this lack of data.  We present results for which ADAS is configured to ingest profiles from MODIS Atmospheric Profile Level 2 products, which provide data over the observation-starved ocean regions. We examine the spatial correlation characteristics of the satellite swaths, compare the retrieved profiles with the 20-km RUC background field, and evaluate the retrieved profiles by comparing with synchronous upper air data.  Our work is supported by a NOAA/UCAR grant.
