The National Science Foundation Office of Integrative Activities awarded The Regents of the University of Colorado $240,000 on September 1, 2026, under the Geosciences program (CFDA 47.050) to model space weather impacts on Earth's hydrogen exosphere through physics-based and machine learning methods. The research team will combine exosphere modeling, machine learning techniques, and ultraviolet observations to determine how geomagnetic storms modify the density and energy distribution of exospheric hydrogen. The approach uses a physics-based exosphere model to simulate global neutral hydrogen under quiet and disturbed space weather conditions, driven by thermospheric boundary conditions and coupled with inner-magnetospheric plasma populations to quantify thermal processes, solar radiation pressure, and charge exchange effects within the plasmasphere and ring-current ions. Model results will be validated against Lyman-alpha observations of the geocorona. The work addresses current knowledge gaps that limit understanding of atmospheric escape, interpretation of geocoronal ultraviolet observations, and constraints on satellite drag and orbital lifetime estimates, while building a technically skilled STEM workforce. Work is performed in Boulder, Colorado with a period of performance from September 1, 2026 through August 31, 2029.
