Description
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 Obs4MIPs program (Teixeira et al., 2014).
