An assessment of the FGGE satellite observing system during SOP-1.

Abstract

Investigates the degree to which data from the spaceborne FGGE observing systems are able to determine the complete state of the atmosphere when incorporated into a global objective analysis cycle. Three data assimilation experiments are performed with the Goddard Laboratory for Atmospheric Sciences (GLAS) analysis/forecast system, using different combinations of the FGGE level II-b data collected during the first Special Observing Period (SOP)-1, 5 Jan through 5 March 1979. Forecast impact results from the initial states of these assimilation cycles show the geographical influence of the FGGE satellite observing system on short- to medium-range (two to five days) weather forecasting.-from Authors
