Welcome to the Modeling and Assimilation Data and Information Services Center (MDISC).
Atmospheric, land and ocean observations from satellites, aircrafts, ships, and other sources are grouped, modeled or assimilated into various time scales varying from hourly to multi decadal and processed for visualization and analysis for user community. Assimilated data products are available from the GES DISC.
The Goddard Earth Observing System (GEOS) Data Assimilation System (DAS) is used to generate meteorological data assimilation products in support of NASA instrument teams, NASA's research programs, field campaigns, and as a contribution to U.S. weather and climate research. In addition to near-real-time products, the Global Modeling and Assimilation Office (GMAO) is using version 5 of the GEOS DAS (GEOS-5 DAS) for a retrospective atmospheric analysis for the satellite period (1979 - present). This product, the Modern Era Retrospective-analysis for Research and Applications (MERRA) is available online through the MDISC.
Sign up for the MERRA listserv to receive announcements on the latest data information, tools and services that become available, data announcements from GMAO and more! Contact the GES DISC User Services to be added to the list.
Users can contact staff with questions on the data, data processing and science. Send questions to merra-questions@listserv.gsfc.nasa.gov.
More data will become available from the GES DISC in the future.
