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

Overview

Field of Science:
Earth Science

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.

In this research opportunity, 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. An example: the Arctic is releasing greenhouse gases because of permafrost melt.

The response to radiative forcing is magnified by the water vapor feedback. The scholar will spectrally decompose the observed water vapor feedback. The greenhouse gas radiative forcing and water vapor feedback derived from AIRS will be compared to CMIP6 model estimates, as consistent with the Obs4

MIPs program (Teixeira et al., 2014).
