NASA Postdoctoral Program - Assimilation of Hyperspectral Infrared Radiance Observations in the GEOS

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. This specific opportunity focuses on the usage of infrared radiance observations to improve atmospheric states and model forecasts within the Goddard Earth Observing System (GEOS) global 4D hybrid Ensemble-Variational data assimilation system. The position is located at the Global Modeling and Data Assimilation Office (GMAO) and involves assimilating hyperspectral infrared satellite radiance data that have significant impact on reducing model forecast errors and constraining atmospheric states. Proposals are particularly encouraged that focus on assimilation of radiance data from new hyperspectral infrared instruments such as IASI-NG, MTG-IRS, enhancement of CrIS radiance assimilation algorithms, and the use of machine learning methods to cope with model biases. This opportunity is closed to Senior Fellows who are 5 years or more past their PhD.
