Technical Memorandum on Atmospheric Reanalyses is now available

The NASA Technical Memorandum, Atmospheric Reanalyses—Recent Progress and Prospects for the Future. A Report from a Technical Workshop, April 2010 (TM—2012-104606-Vol 29) is now available.

In April 2010, developers representing each of the major reanalysis centers met at Goddard to discuss technical issues—system advances and lessons learned—associated with recent and ongoing atmospheric reanalyses and plans for the future. The meeting included overviews of each center's development efforts, a discussion of the issues in observations, models and data assimilation, and, finally, identification of priorities for future directions and potential areas of collaboration. This report summarizes the deliberations and recommendations from the meeting as well as some advances since the workshop.

The Global Modeling and Assimilation Office (GMAO) works to maximize the impact of satellite observations in climate, weather and atmospheric composition prediction using comprehensive global models and data assimilation. To achieve this goal, the GMAO develops models and assimilation systems, generates products to support NASA instrument teams and the NASA Earth science program, and undertakes scientific research to inform system development pathways.

Assimilation systems have been developed for the atmosphere, ocean, and land surface. GMAO's long-term goal is an integrated Earth system model and assimilation system that treats the individual components in a more coupled and interactive manner. GMAO works within numerous national and international collaborations to support its mission.
