The Atmospheric Infrared Sounder (AIRS): Greenhouse gas radiative forcing and water vapor feedback

This NASA Postdoctoral Program fellowship offers a unique research opportunity to engage in ongoing NASA research projects. The scholar will use satellite observations of the top-of-atmosphere infrared spectrum from the Atmospheric Infrared Sounder (AIRS) instrument to study changes in the outgoing longwave radiation. Radiative forcing and feedbacks arising from greenhouse gas changes will be analyzed. AIRS data provides an opportunity to study local radiative forcing changes, including Arctic greenhouse gas releases from permafrost melt. The scholar will spectrally decompose the observed water vapor feedback and compare AIRS-derived greenhouse gas radiative forcing and water vapor feedback to CMIP6 model estimates. The NASA Postdoctoral Program provides competitive one- to three-year fellowships designed to advance NASA's missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
