- This National Science Foundation project grant of $372,870 supports research into aerosol-cloud-turbulence interactions through numerical simulation and experimental chamber studies. Awarded on September 1, 2022 under the Geosciences program (CFDA 47.050), the three-year award to the University of Notre Dame will use high-resolution numerical modeling and experiments at the PI Chamber facility to examine questions around aerosol hygroscopicity, supersaturation fluctuations, droplet settling...
- This $120,000 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research into gigantic jets (GJs), large electrical discharges that couple the troposphere and ionosphere. Duke University will construct climatologies of GJs by developing a machine learning classifier to detect them by the thousands using data from the Geostationary Lightning Mapper. Validation will incorporate ground-based radio networks to filter non-lightning events and determine...
- This $637,638 Project Grant awarded by the National Science Foundation's Division of Atmospheric and Geospace Sciences under the Geosciences program (CFDA 47.050) supports research at Dartmouth College to improve the understanding of the interconnection between magnetic reconnection and turbulence in plasma systems. The key objectives are to: 1) Identify electron-only reconnection in kinetic turbulence, 2) Examine the evolution of electron-only reconnection in Alfvenic turbulence, and 3)...
This federal Project Grant award of $341,107, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), will support a collaborative research study at The Johns Hopkins University investigating the role of turbulence in the development of corona discharges inside clouds. The research team plans to perform controlled laboratory experiments using a homogeneous and isotropic turbulence chamber to study how multiscale electric fields develop and intensify in particle-laden turbulence, and the intrinsic connection between fluctuating electric fields and the occurrence of visible and subvisible discharges. The study has implications for understanding lightning, atmospheric chemistry, and industrial processes, and may provide insights relevant for future planetary science missions. The project is scheduled to run from September 1, 2025, to August 31, 2027.
