The National Science Foundation (NSF) Geosciences Program (CFDA 47.050) awarded a $538,591 Project Grant to Cornell University to investigate the relationship between tropical sea surface temperatures and the temperature and composition of the Tropical Tropopause Layer (TTL), which acts as a gateway to the stratosphere. The research involves using idealized modeling experiments with specialized climate models to reconcile two competing theories on how tropical sea surface temperature patterns influence TTL temperature, water vapor, and ozone levels. The findings will provide insights into long-term TTL trends and their implications for stratospheric ozone and greenhouse gas dynamics. This grant also supports the participation of an undergraduate student in the Cornell GEOPaths Geoscience Learning Ecosystem (CORGGLE) summer bridge program and training for a postdoctoral researcher, contributing to STEM workforce development.
