Description Description:
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, satellite radiances play an important role in constraining atmospheric states and reducing model forecast errors. Traditionally only clear-sky radiances had been used in data assimilation systems due to limitations of model and radiative transfer models (RTM). However, the importance of including radiance data with fields of view (FOVs) affected by clouds and precipitation in a data assimilation system is obvious, as these data are usually associated with meteorologically important areas. With the advances of model microphysics and RTM, all-sky microwave radiance assimilation has been realized operationally in major NWP centers and GMAO, but all-sky infrared radiance assimilation is still in research stage. This NPP opportunity invites proposals that are focused on the usages of radiance observations to improve atmospheric states and model forecasts, especially, proposals with the following foci:
Exploration of methodology for all-sky geostationary or hyperspectral infrared radiance assimilation
Enhancement of all-sky microwave radiance assimilation algorithm
are highly encouraged.
