About this award

Morgan State University has been awarded a $210,002 research grant by a civilian federal agency (Shared Services Center) to investigate inter-model differences in hydroxyl radical (OH) distributions and their interannual variability in global chemistry climate models. The research aims to understand how variations in atmospheric dynamics and meteorological processes across different models contribute to discrepancies in simulated OH, a critical tropospheric oxidant that controls methane lifetime and influences numerous atmospheric constituents. Rather than focusing solely on chemical process differences, this project will employ statistical analyses and machine learning techniques to identify relationships between meteorological conditions, tracer distributions, and simulated OH concentrations, while also conducting sensitivity studies to quantify the impact of specific dynamic processes.

The contract, awarded on April 21, 2023, with a completion date of April 20, 2026, will be performed in Baltimore, Maryland at Morgan State University. The research deliverables include novel, process-based diagnostics that could reduce uncertainties in chemistry-climate feedbacks affecting methane lifetime and improve the simulation of atmosphere constituents influenced by OH. This award reflects the university's continued engagement in atmospheric science and climate research, contributing to better understanding of key tropospheric processes that impact global climate models and inform climate change mitigation strategies. No set-aside designation was used for this contract award.
