GEOS- 5 - CloudSat Intercomparisons

This study utilizes global analyses of atmosphere obtained from the new GEOS-5 Data Assimilation System (DAS) developed for GMAO's Modern Era Retrospective-analysis for Research and Applications (MERRA) to examine the relationships between cloud parameters observed by the CloudSat satellite and predictors of convective cloud structure derived from MERRA retrospective analyses.

An analysis of convective transport and parameter sensitivity in a single column version of the GEOS-5, Atmospheric General Circulation Model

Modeled transport of CO and CO2 is used to evaluate parameterizations in GEOS-5 and to identify which parameters have the greatest impact on trace gas transport in three different storms.

Observation Sensitivity Calculations using the Adjoint of the Gridpoint Statistical Interpolation (GSI) Analysis System

GMAO scientists have developed a new formulation of the GEOS-5 atmospheric data assimilation system to understand and improve the way observations are used in weather and climate forecasts.
