The development and evaluation of an algorithm to map GOES-12 SSTs to near surface over-ocean air temperatures. C. CALVERT and S. LAZARUS. Dept. of Marine and Environmental Systems, Florida Institute of Technology, Melbourne, FL 32901. The primary sources of near surface air temperatures over oceans are obtained from buoy and ship weather reports. Unfortunately, there are few buoys and ships at any given time, making it difficult to produce adequate air temperature analyses over the ocean east of Florida. Here, we present initial results using data spanning a five-year period from 1998-2002 from two offshore NOAA weather buoys east of Cape Canaveral. We can estimate coefficients from a multilinear regression algorithm using various combinations of predictors (e.g., wind speed, SST, etc.) and GOES-12 SSTs. The goal is to apply the hourly GOES-12 SST analysis to produce an initial guess field of over-ocean air temperature which will be used for assimilation into the operational NWS Melbourne office mesoscale forecast model.
