This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support fundamental research on atmospheric particle nucleation and growth under conditions found in the free troposphere. The $356,844 award to Carnegie Mellon University will investigate the interactions between oxidized organic compounds and inorganic acids leading to new-particle formation in the cold upper troposphere, as well as the low-temperature growth of particles through the...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $128,741 to Carnegie Mellon University to support the participation of U.S. scientists in the international HALO-South field campaign. The goal is to measure clouds and aerosols over the Southern Ocean in order to better understand the sources and sinks of cloud-nucleating aerosols in this region, which is key for understanding Earth's radiation budget and global cloud feedbacks. The...
Carnegie Mellon University was awarded a $853,186 project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences. The grant is part of NSF's Geosciences program (CFDA 47.050), which supports basic research to enhance understanding of the integrated Earth system. Under the grant, Carnegie Mellon University will conduct research from January 2022 through December 2024 to examine interactions between organic oxidation and acid-base chemistry during particle...
The National Science Foundation awarded a $533,566 Project Grant to the University of Miami under the Geosciences program (CFDA 47.050) to support the acquisition of an Aerosol Characterization System. The System will be operated at the University's Ragged Point site in Barbados and is expected to open new research avenues related to the transport of African dust to the Americas, the impact of ocean-derived organic aerosols in the marine boundary layer, wildfire smoke, and cloud and radiation...
This Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), provides $783,700 to Carnegie Mellon University to acquire an Aerodyne Vocus Proton Transfer Reaction-Mass Spectrometer (Vocus PTR-MS). This advanced mass spectrometer will enable simultaneous measurement of hundreds to thousands of gas and particle-phase organic compounds in the atmosphere, including highly reactive free radicals and lightly oxidized compounds that contribute to aerosol...
This Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), focuses on assessing the role of atmospheric new particle formation in influencing the pre-industrial climate. The $236,059 award to Carnegie Mellon University, effective August 1, 2025 through July 31, 2030, will develop a new parameterization of new particle formation that accounts for the role of temperature and atmospheric ions. This research aims to improve the understanding of...
The National Science Foundation (NSF) awarded a $498,014 Project Grant under the Geosciences program (CFDA 47.050) to Stanford University to advance the process-level understanding of how anthropogenic aerosols impact precipitation extremes. Over a 5-year period from June 2025 to May 2030, the project aims to: Enhance the representation of aerosol and cloud microphysics in a global climate model to improve simulation of extreme precipitation events. Investigate the complex impacts of...
This three-year, $454,659 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports the continued membership of three universities in the Cloud Consortium at CERN. The Consortium will study the chemistry and physics that drive new particle formation and growth in Earth's atmosphere using a 26 cubic meter stainless steel chamber. Over the grant period, research will focus on chemical mechanisms generating extremely low volatility organic compounds that can...
This three-year, $348,116 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports the continued membership of three universities in the Cloud Consortium at CERN. The consortium studies the chemistry and physics that drive new particle formation and growth in Earth's atmosphere using a 26 cubic meter stainless steel chamber with precise temperature and humidity control. Over the grant period, the awardee Carnegie Mellon University and sub-awardees...
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...
