This $368,409 Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research project investigating the sources and impacts of large-scale gravity waves in the thermosphere. The research aims to quantify the relative contributions of gravity wave sources from the lower atmosphere versus above the stratosphere, and analyze the effects of these waves on atmospheric tides, planetary waves, and large-scale circulations. The project will leverage satellite observations and simulations using the Specified-Dynamics Whole Atmosphere Community Climate Model with Thermosphere and Ionosphere Extension (SD-WACCM-X) to advance understanding of gravity wave coupling processes and the lower atmospheric influences on space weather. No sub-awards are planned under this grant, which runs from January 1, 2025 to December 31, 2027 and is led by the University of Colorado.
