This Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to advance the understanding of extreme precipitation events and their impacts. The award of $870,213, effective from September 1, 2025 to August 31, 2030, will address three key questions: 1) how precipitation distribution depends on spatial and temporal scales, 2) the comparative roles of aerosol and greenhouse gas forcing in precipitation distribution, and 3) the impact...
This $498,014 federal Project Grant award was provided by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050) to The Leland Stanford Junior University (Stanford University). The award period is from June 1, 2025 to May 31, 2030. The overarching objective of this project is to advance the process-level understanding of how anthropogenic aerosols impact precipitation extremes. Key activities include enhancing the representations of aerosol and cloud microphysics in...
This National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences Project Grant, under CFDA program 47.050 - Geosciences, provides $291,216 in funding to the Desert Research Institute (DRI), part of the Nevada System of Higher Education (NSHE), to develop an urban modeling system that examines the interaction between the urban heat island, outdoor water, and air pollution. The project aims to improve understanding of how cities and their excess heat, vegetation irrigation, and...
This National Science Foundation (NSF) Geosciences program (CFDA 47.050) project grant award of $399,134 aims to study the combined role of urban expansion and climate change on extreme summer rainfall in two rapidly growing metropolitan areas, Austin, TX and Phoenix, AZ. The project will utilize advanced numerical modeling to characterize the physical processes driving changes in extreme summer rainfall patterns, and disseminate the findings to local stakeholders to inform infrastructure...
This National Science Foundation (NSF) CAREER grant, awarded under the Geosciences program (CFDA 47.050), provides $150,354 to Texas A&M University to conduct a comprehensive study on atmospheric micro- and nano-plastic particles (MNPPs). The project aims to: 1) quantify the real-time and offline concentrations, spatial distribution, and sources of major atmospheric MNPPs; 2) characterize the atmospheric reaction kinetics, chemical reactivity, and decomposition products of MNPPs through...
This $1,185,628 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) funds research at the University of Miami Rosenstiel School of Marine and Atmospheric Science examining the evolving role of the ocean and atmosphere in decadal to multidecadal climate variability modes. The principal investigators aim to determine if climate modes characterized by alternating 20-40 year warming and cooling episodes in the North Atlantic, such as the Atlantic Multidecadal...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $891,928 to Carnegie Mellon University (CMU) supports research to improve the understanding of global aerosol concentrations and composition. Key objectives include: Building a global network of U.S. embassy partners and local stakeholders to enable worldwide data analysis and interpretation of aerosol measurements. Quantifying concentrations and temporal trends of major inorganic ions, black...
This $1,482,996 National Science Foundation project grant supports research at the University of California, Los Angeles to diagnose and understand the mechanisms behind warm season extreme weather over central and intermountain United States. The grant is funded through the NSF's Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through atmospheric, earth, and ocean sciences support. Specifically, the UCLA researchers will apply statistical...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $100,000 over 2 years to investigate the oxidation chemistry of organic aerosols in the atmosphere and its impact on their optical properties. The research will utilize innovative triple oxygen isotope measurements to elucidate the specific oxidation pathways that contribute to changes in aerosol composition, with the goal of understanding how these compositional changes affect...
