Earth Science: Data Assimilation for Earth Science

National Aeronautics and Space Administration (NASA)
Greenbelt, MD Full Time
POSTED ON 9/1/2026

About the NASA Postdoctoral Program

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

Description:

This opportunity is closed to applicants who are Senior Fellows (5-years or more past PhD).

The Global Modeling and Assimilation Office (GMAO) supports the modeling and data assimilation needs of NASA's Earth science mission, to characterize, understand, and predict how the Earth as a system is changing on both weather and climate time scales. The GMAO develops the Goddard Earth Observing System (GEOS) model and data assimilation system, including comprehensive atmosphere, ocean, ice, and land surface components.   Along with the analysis and prediction of weather and seasonal climate states, GMAO's efforts encompass atmospheric air quality, ocean biogeochemistry, and the carbon cycle. Potential research activities include:  

  • developing the underlying model components to improve the representations of processes and the coupling among different processes in the Earth system  
  • development of  advanced modeling techniques based on Artificial Intelligence/Machine Learning  
  • developing and applying new techniques to assimilate NASA's Earth observations   and assessing their impacts on prediction on timescales that span weather to seasons
  • focused model experimentation to identify the mechanisms of change in the Earth system.
