of Versions 5.0.1, 5.1.0, and 5.2.0 " (DRAFT)
RESEARCH BRIEFS
 Convective Transport of Trace Gases
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.

WHAT'S NEW
08.19.2008 - GEOS-5 - CloudSat Intercomparisons
A new study utilizes global analyses of the 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 re-analyses.

02.13.2008 - GMAO Supports ARCTAS Campaign in Spring/Summer 2008
The Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) campaign took place during the Spring and Summer of 2008. The GMAO, in collaboration with SIVO, The Atmospheric Chemistry and Dynamics Branch,and NCCS provided chemical forecast support for aiding flight planning and data analysis in the field.
