Report on Data Assimilation Experiments Using the RTOVS Retrievals

Abstract

NOGAPS's short to medium range weather forecasts, which started from analysis assimilating NESDIS's new satellite temperature retrievals, demonstrate less forecast skill than forecasts using the old temperature retrievals. Several data assimilation tests are discussed in which different retrieved satellite temperature errors are set and restrictions of the satellite temperature data are set in the Northern Hemisphere. The recommendation of this report is that with the current NOGAPS data assimilation/forecast system NESDIS RTOVS temperature retrievals not be used in the Northern Hemisphere.
