Assimilation of Hyperspectral Infrared Radiance Observations in the GEOS

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 Goddard Earth Observing System (GEOS) global 4D hybrid Ensemble-Variational (EnVar) data assimilation system at Global Modeling and Data Assimilation Office (GMAO) has been supporting NASA research and Earth Science missions. Among the millions of observations assimilated at each analysis cycle in the GEOS system, hyperspectral infrared satellite radiance data have been used extensively and they have proved significant impact on reducing model forecast errors and constraining atmospheric states. This NPP opportunity invites proposals that are focused on the usages of IR radiance observations to improve atmospheric states and model forecasts, especially, proposals with the following foci:

• Assimilation of radiance data from new hyperspectral infrared instruments such as IASI-NG, MTG-IRS
• Enhancement of CrIS radiance assimilation algorithm
• Use machine learning methods to cope with model biases
