Abstract: Recently, HIRS2/MSU data have been used at the Goddard Laboratory for Atmospheres(GLA) to generate global precipitation estimates. A synergistic mix of the GLA precipitation, together with the global wind and moisture ...

Abstract: Ensembles of assimilation runs were used to assess the sensitivity of the GEOS-1 (Goddard Earth Observing System?Version 1) data assimilation system to data gaps and changes in initial conditions. Perturbations from a ...

Abstract: At this time, most current data assimilation systems use dewpoint depression data, converted to an appropriate moisture variable (relative humidity or mixing ratio), provided by rawinsondes as the lone source of moisture ...

Abstract: General Circulation Model (GCM) experiments have been performed to determine mechanisms that maintained the blocking episode in the Australian-New Zealand region during the period 8?22 June 1982. A control forecast reproduces ...

Abstract: The Data Assimilation Office at NASA's Goddard Space Flight Center is currently producing a multiyear gridded global atmospheric dataset for use in climate research, including tropospheric chemistry applications. The data, ...

Abstract: Global precipitation estimates derived from satellite data at the Goddard Laboratory for Atmospheres for 1979?80 were used to explore time variations in global precipitation. Time series of the area-averaged precipitation ...

Abstract: Systematic prediction errors of the Goddard Laboratory for Atmospheres (GLA) forecast system are reduced when the higher-resolution (2° ? 2.5°) model version is used. Based on a budget analysis of the 200-mb eddy streamfunction, ...

Abstract: According to the atmospheric water balance equation, the divergence of the water vapor flux is responsible for the exchange of water vapor between its source and sink regions. Because the water vapor flux divergence is ...
