GMAO Data Products
GMAO generates and distributes a number of products that either make extensive use of NASA's satellite observations, provide support to satellite missions and field campaigns, or help with the planning for new missions. These products also support researchers funded by NASA and others. This page provides quick links to these products: more details are found on the thematic pages.

All GMAO data products are experimental and are intended for use by NASA investigators and scientific researchers. To comply with NASA's Earth Science data distribution policy (https://science.nasa.gov/earth-science/earth-science-data/data-information-policy), GEOS datasets are shared for use by the research and applications communities, private industry, academia, and the general public.
GMAO product generation uses HEC resources at Goddard Space Flight Center's NASA Center For Climate Simulation (NCCS). While we make every effort to maintain data continuity, GMAO is not an operational center and consequently has no back-up capabilities that ensure data production or distribution continues when the systems are down.
