This is a $745,825.75 grant awarded by NASA to Columbia University to conduct research on variability and trends in tropospheric oxidation and its interactions with regional air quality, global atmospheric composition, and climate. The research aims to advance the understanding of oxidation chemistry in the global troposphere, identify trends and variability in oxidation regimes induced by changes in pollutant emissions and climate variability, and construct a seasonal climatology of hydroxyl radical (OH) sensitivity. This grant is part of NASA's broader efforts to study the distributions, trends, and variability in near-term climate forcing agents such as ozone and aerosols. The research will leverage satellite data from the NASA Aura mission and suborbital measurements to investigate oxidation in polluted regions, remote backgrounds, and aged biomass burning plumes. This grant does not have a set-aside designation and is awarded to the Trustees of Columbia University, a renowned private research institution with extensive experience in conducting federal contract and grant work across scientific and technical domains.
