GMAO’s “Notion of Ocean Motion” Demonstration Part of NASA’s Earth Day 2018

Members of the GMAO team took part in NASA’s Earth Day activities held in the Main Hall of Washington DC’s Union Station on April 19 and 20, 2018.

MERRA-2 AMIP data (M2AMIP) now available

The GMAO is now providing MERRA-2 AMIP data (M2AMIP) a 10-member GCM experiment based on the climate forcing configuration used in MERRA-2. All modeling features in the model are identical to MERRA-2, except for the lack of observational analysis, and provides the model's realization of present day climate. Most MERRA-2 variables are available. For one member, hourly data have been preserved, otherwise the 10 members are monthly data, and include an ensemble mean.

GMAO continues to provide support for ASPIRE

GMAO once again provided customized forecast support for the launch of a Black Brant IX suborbital sounding rocket carrying the Advanced Supersonic Parachute Inflation Research Experiment (ASPIRE). ASPIRE 2 was successfully launched at 12:19 p.m. EDT, March 31, 2018, from NASA’s Wallops Flight Facility.

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.
