Project Grant 2528650
- This federal Project Grant award of $537,789.00 was provided by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) to the University of California, Berkeley to conduct research on understanding past and future trends in tropical relative humidity over land. The overarching goal of the research is to develop a theoretical framework to account for observed changes in relative humidity over tropical continents, particularly in regions like India, and provide estimates for...
- This $1,201,906 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund research at Cornell University to address three fundamental questions aimed at advancing the understanding of extreme precipitation events. The key objectives are to: 1) investigate how precipitation distribution depends on spatial and temporal scales, 2) assess the comparative roles of aerosol and greenhouse gas forcing in determining precipitation distribution, and 3)...
- This $202,000 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support a research project to reconstruct past variations in vapor pressure deficit (VPD) in the southwestern United States over the last 500 years. The project will use oxygen isotope measurements in tree rings to develop long-term VPD reconstructions, which will then be compared to climate model simulations to assess the drivers of VPD changes and determine if the recent VPD...
- This $695,471 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research at the University of Vermont & State Agricultural College (UVM) to investigate the effects of relative humidity on organic new particle formation in the atmosphere. The key objectives are to: 1) explore the relative humidity sensitivity of new particle formation for representative atmospheric organic aerosol precursors, and 2) use chemical scrubbers to identify the...
- This $270,754 Project Grant award from the National Science Foundation's (NSF) Biological Sciences program supports collaborative research to investigate the impacts of the ongoing megadrought in the American West on soil moisture, ecosystem carbon-water cycling, and remote sensing capabilities. The research team, led by the Trustees of Indiana University, will synthesize hundreds of long-term soil moisture measurements with remotely-sensed data and eddy covariance tower observations to...
- This Project Grant award of $945,558 from the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of Texas at Austin supports research on the impacts of aerosols on multivariate climate hazards. The key objectives are to: 1) develop methodologies to uncover the influence of aerosols on extreme events like fire weather, humid-heat, and drought using climate models; and 2) educate the next generation of climate researchers on the factors contributing to these...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award to Syracuse University totaling $547,085 provides funding to determine the sensitivity of eastern North American hydroclimate to climate forcings and feedbacks during the last deglaciation period. The researchers will measure stable isotopes in leaf waxes archived in lake sediments along a latitudinal gradient to track northward moisture import into the region by the North Atlantic Subtropical High....
- This $695,079 Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), aims to enhance the understanding of drought trends and soil moisture-precipitation feedbacks in the Congo rainforest. The research will investigate the counterintuitive relationship between decreasing precipitation and increasing thunderstorm activity, referred to as the "Congo Precipitation Paradox." The study, conducted by The Research Foundation for the State University...
- This $1,389,411 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports the continuing research efforts of the Principal Investigator to understand the probability distribution of rainfall intensity and its relationship to climate change. The key objectives include: Explaining why increases in precipitation intensity in a warming climate exceed expectations based solely on increased water vapor content. Exploring how the suppression of convection due...
- This Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences, under the Geosciences program (CFDA 47.050), will provide $417,242 to The Research Foundation for The State University of New York (RF-SUNY) from September 1, 2023 to August 31, 2026 to conduct collaborative research on the 50,000-year history of the Indian Summer Monsoon (ISM). The research will focus on analyzing sediment cores from Loktak Lake in northeast India to reconstruct past changes in the...
This Project Grant award of $599,937 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a critical assessment of the recent rapid decline in land surface relative humidity (RH) and its impacts. The principal investigator at The Research Foundation for the State University of New York (RF-SUNY) will lead this research project from September 2025 through August 2028. The project aims to explain the causes of the observed RH decline, which has major implications for human comfort, health, drought, and wildfires. The researchers will homogenize global monthly RH data since 1973 using advanced statistical methods to detect and remove discontinuities, quantifying the impact on the recent RH trend. They will also analyze the relationships between RH, cloud cover, precipitation, surface heat fluxes, and soil moisture to investigate if land-air interactions have amplified the RH decrease. This comprehensive analysis is expected to provide critical insights into the driving factors behind the rapid RH decline, benefiting research on human health, drought, and wildfires in the U.S. and other regions.
