This $254,882 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research investigating the sensitivity of reactive halogen abundance to glacial-interglacial climate change. Over a three-year period ending June 2025, the University of Rochester will examine how blowing snow on sea ice may explain increased sodium ion observations in ice cores over glacial-interglacial timescales. The project will also identify major drivers for reactive halogen...
This $732,679 federal Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) aims to improve the understanding of atmospheric methane oxidation by hydroxyl and chlorine radicals. The project will involve fabricating a laboratory photochemical reactor to study the kinetic isotope effects of these reactions under a wide range of experimental conditions, including temperature, pressure, and reactant concentrations. The primary analytical techniques will...
This three-year project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, totaling $660,762, will fund research into atmospheric chlorine oxidation of hydrocarbons emitted from Alaska's North Slope oil fields. The research, to be conducted by the University of Michigan from June 2022 to May 2025, aims to investigate the dominant mechanisms of chlorine oxidation of atmospheric trace gases through three objectives: identifying and quantifying reactive...
This $443,926 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund research into the physical and chemical controls on aerobic methane oxidation. The University of Rochester will investigate variables that influence the oxidation of methane in oxygenated natural waters to better understand this important greenhouse gas sink. Laboratory experiments and field work on the Great Lakes and US Atlantic coast will evaluate the kinetics of aerobic methane...
This $649,388 Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences, under the Geosciences program (CFDA 47.050), will fund research exploring the impact of future land use change on global air quality and nutrient deposition. Specifically, the awardee, the Massachusetts Institute of Technology, will couple land use output from the Community Land Model simulations, driven by Shared Socioeconomic Pathways scenarios, to the GEOS-Chem global chemical...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $603,364 project grant to the University of Rochester to support collaborative research on improving estimates of geologic methane emissions to the atmosphere from microseepage. The three-year award, made under the Geosciences program (CFDA 47.050), will fund research from February 2021 through January 2024 to strengthen understanding of the integrated Earth system through expanding knowledge of...
The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $199,997 Project Grant to The Research Foundation For The State University Of New York, doing business as Suny ESF, under the NSF Geosciences federal grant program (CFDA 47.050) with a period of performance from July 1, 2023 to June 30, 2024. The grant is supporting a RAPID project to characterize the sources and chemistry of nitrogen oxides, nitrous acid, and particulate nitrate during the AEROMMA...
This $120,981 National Science Foundation project grant supports collaborative research by Aerodyne Research Inc. to investigate atmospheric chlorine oxidation of hydrocarbons emitted from Alaska's North Slope oil fields. The research aims to identify reactive volatile organic compounds and quantify their chlorine reactivity in the Arctic oil field environment. It will also identify oxygenated volatile organic compounds and secondary organic aerosol products of VOC-chlorine reactions. Scientists...
This $1.5 million National Science Foundation project grant supports research into secondary marine aerosol precursors and their links to aerosol growth during Arctic sea ice melt onset. Funded under the Geosciences program (CFDA 47.050), the goal is to advance understanding of secondary marine aerosol formation in the atmosphere and its impact on cloud properties and climate. Colorado State University will conduct measurements of volatile organic compounds and reduced sulfur compounds aboard...
This Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) provides $392,649 to Cornell University to conduct research on designing marine cloud brightening (MCB) approaches to help mitigate climate change impacts. The goal is to develop systematic design principles and optimization tools for MCB, and to assess how MCB could complement stratospheric aerosol intervention (SAI) to better manage future climate risks. The research aims to fill gaps in...
