The GMAO Research Site

The Global Modeling and Assimilation Office (GMAO) supports NASA's Earth Science mission. Activities in Earth System modeling and data assimilation aim to maximize the impact of satellite observations on analyses and predictions of the atmosphere, ocean, land and cryosphere.

Major Advance in MJO Prediction Skill in GMAO’s Near Real Time Seasonal Forecasts

The Madden-Julian Oscillation (MJO) is predicted much more realistically in version 2 of the NASA GEOS-S2S system (GEOS-S2S-2) than in the older version (GEOS-S2S-1).

GEOS Captures Tropical Cyclone-Like System Trudy over the Mediterranean Sea

A cyclone type is found primarily in the Mediterranean Sea and is thus frequently referred to as a Medicane. Until now our models could not fully resolve these processes. The current GEOS FP did show all the ingredients necessary to trigger Medicane Trudy. This may be the first Mediterranean Medicane correctly forecast and analyzed by NASA's GEOS.

Developing an Ozone Climate Data Record from Assimilation of High-Resolution Satellite Observations

Assimilation of high-resolution satellite observations can provide accurate representations of stratospheric ozone on time scales ranging from hours to decades.

Global Transport of Smoke from Australian Bushfires

The transport of the Australian bushfire smoke plumes around the global has accelerated through deep vertical transport into the upper troposphere and even the lowermost stratosphere, leading to long-range transport around the globe. [GEOS-FP animation]
