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...
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...
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 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 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...
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 $389,417 National Science Foundation project grant supports atmospheric particle formation research at Augsburg University from December 2022 through November 2025 under the Geosciences program (CFDA 47.050). The university will conduct laboratory experiments to enhance understanding of new particle formation processes in the atmosphere, focusing on sulfuric acid/water and ammonia systems as well as oxidation products from organic compounds. Experiments using two flow reactors will...
This Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) provides $695,471.00 to the University of Vermont & State Agricultural College to conduct research on the impacts of relative humidity on organic new particle formation in the atmosphere. The primary goals of this 3-year project, which runs from June 15, 2025 to May 31, 2028, are to: 1) explore the sensitivity of new particle formation to relative humidity for representative atmospheric...
This $941,193 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to further develop a theory on the invariance of cloud size distribution under varying climate conditions. The research aims to evaluate whether certain cloud properties, such as the relationship between cloud size and number, remain consistent despite changes in atmospheric climate and chemical composition. The work seeks to understand the underlying physical mechanisms...
