GMAO Products
GMAO generates GEOS-5 data products in near real time or reanalysis modes in support of diverse user communities. Starting in February 2013, GEOS-5 forward processing is conducted in two separate streams. These are called (1) Forward Processing (FP) and (2) Forward Processing for Instrument Teams (FP-IT).
The FP stream generates forecasts as well as assimilation products using the most current system approved for near-real-time production. FP products are primarily used for real time support for NASA field campaigns, support for NASA science, GEOS system evaluation, and interaction with other data assimilation centers. The FP system is updated as the GEOS system improves and is transitioned to production status.
The FP-IT stream generates only assimilation products. FP-IT processing uses a "semi-frozen" GEOS-5 system to ensure long-term continuity and reproducibility. FP-IT products serve primarily the NASA EOS Instrument Teams who require stable products over a long period of time. Reprocessing of historical periods using the FP-IT system is conducted as needed in coordination with Instrument Teams.
The product generation uses HEC resources at GSFC's NASA Center For Climate Simulation (NCCS).

• [ 30 January 2013 ] PLEASE NOTE: Production of GEOS-5.2.0 will end on May 2, 2013.
• [ 30 January 2013 ] GEOS-5 FP data production is expected to start in February, 2013.
IMPORTANT: Forecasts using the GEOS system are experimental and are produced for research purposes only. Use of these forecasts for purposes other than research is not recommended.
