- The National Science Foundation (NSF) awarded a Project Grant of $367,399 to the University of Georgia Research Foundation, Inc. (UGA Research Foundation) under the NSF Geosciences program (CFDA 47.050). This 3-year project, starting in June 2024, will conduct a time-series study of aerosol trace elements in the North Atlantic Ocean near Bermuda. The key objectives are to: Analyze temporal variations in the size distribution of aerosol iron and other bioactive trace elements, and link these to...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded the University of Maryland, College Park $799,030 on March 1, 2026, under the Geosciences program (CFDA 47.050) to quantify how cloud-surface coupling influences aerosol-cloud interactions across varying land surface types and atmospheric conditions. The research team will use ground, airborne, and space-based sensor data combined with machine learning and numerical simulations to determine whether theory...
- This National Science Foundation (NSF) Project Grant award, funded under the Geosciences program (CFDA 47.050), will support a two-year time-series study of size-fractionated aerosol samples collected near Bermuda in the North Atlantic Ocean. The $571,384 award to the University of Delaware aims to: 1) analyze temporal variations in the size distribution of aerosol trace elements like iron, 2) quantify lower and upper estimates of potentially bioavailable iron, 3) investigate the chemical...
- Federal Grant Award Summary The National Science Foundation's Division of Atmospheric and Geospace Sciences awarded a $202,000 Project Grant under the Geosciences program (CFDA 47.050) effective June 1, 2025, through May 31, 2027, to support postdoctoral research on giant sea salt aerosol (GSSA) production and atmospheric distribution. The award funds a three-pronged research initiative conducted in Honolulu, Hawaii, combining observational measurements with numerical modeling to address a...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded the Desert Research Institute $565,958 on February 1, 2027, to develop and interpret high-resolution aerosol records spanning approximately the past 14,000 years using European ice cores collected from Dôme du Goûter and adjacent drill sites in the French Alps. The project applies state-of-the-art analytical methods and radiometric dating techniques to generate well-dated, high time-resolution records of...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded the Regents of the University of Michigan $397,579 on August 15, 2026, for collaborative research on carbonaceous aerosol sources and properties in the North Atlantic Basin under the Geosciences program (CFDA 47.050). The project investigates carbonaceous aerosol over the North Atlantic that absorbs more sunlight than current models predict, with focus on three main sources: soil-derived organic matter in transported dust, smoke from sub-Saharan wildfires, and marine organic aerosol including material from Sargassum blooms. Field measurements will be collected at Ragged Point in Barbados during two campaigns—one focused on summertime dust transport and one on springtime smoke transport. Research aims to improve understanding of radiative impacts and aerosol-cloud interactions over the tropical Atlantic marine boundary layer, impacts on biogeochemical cycles, and how organic material enhances iron solubility to stimulate marine productivity. Results will support more accurate representations of aerosol and cloud processes in numerical weather prediction and Earth system models. The project includes workforce training opportunities for high school students, undergraduate, and graduate students across multiple U.S. institutions. Work is performed at Ann Arbor, Michigan with a period of performance through July 31, 2029. The award is a Project Grant with no sub-awards planned.
