The National Science Foundation awarded a $599,872 Project Grant to the Massachusetts Institute of Technology under the Geosciences federal grant program (CFDA 47.050). The grant supports research to advance understanding of wildfire impacts on stratospheric chemistry through several linked components. MIT will study the chemical impacts of increased hydrogen bromide solubility in organic aerosols from wildfires and ozone production in stratospheric air from wildfire emissions. Researchers will also examine the long-term decay of aerosols associated with the 2020 Australian wildfires and the evolution and chemistry of specific wildfire events in both hemispheres. MIT will use observations and modeling to assess impacts of concurrent wildfire and volcanic loadings on light extinction and chemistry in the stratosphere. The award provides funding from June 1, 2023 to May 31, 2026 and supports a full-time graduate student and undergraduate student to conduct modeling simulations and collect/analyze satellite and lidar data to advance the research objectives.
