This National Science Foundation Project Grant award of $336,148 provides funding from January 1, 2023 through December 31, 2025 to Montana State University for the development of a prototype diode-laser-based Doppler wind lidar for vertical wind profiling in the lower troposphere. The award advances the Geosciences program's goal of increasing understanding of the integrated Earth system through basic research in atmospheric sciences. Specifically, the university will conduct modeling to...

The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $440,764 Project Grant to Washington State University to study the influences of large turbulent eddies on the validity of the constant flux layer assumption in the unstable atmospheric surface layer. The 3-year project will leverage a field experiment over a large water body in Mississippi to collect a unique dataset that minimizes the influence of advective terms, enabling a more precise examination...

The Massachusetts Institute of Technology Lincoln Laboratory will provide aircraft-derived atmospheric observations to improve weather forecasting models under a $520,500 cooperative agreement from the National Oceanic and Atmospheric Administration. Through the award's two-year period, MIT Lincoln Laboratory will extract meteorological data from commercial aircraft equipped with Mode S transponders using airport surveillance radars. This effort aims to increase the number, spatial resolution,...

The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $126,139 Project Grant to the University of Virginia to advance research on measuring atmospheric turbulence and wind behavior using commercial off-the-shelf multi-rotor drone technology. The 12-month project, which runs from July 15, 2023 to June 30, 2024, aims to investigate the accuracy of drone-based turbulence measurements and how accuracy varies with drone size and weight. The work will be...

This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $380,375.00 to the University of Texas at Dallas (UTD) to study turbulence and sea spray aerosol transport in the marine atmospheric boundary layer of coastal regions. The 3-year project will make field observations using a scanning Doppler lidar and existing meteorological/oceanographic data to quantify limitations in current modeling techniques and identify interactions between waves...

The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $458,858 Project Grant to The Regents of the University of Colorado to support research titled "COLLABORATIVE RESEARCH: NEW PATHWAYS TO ENHANCED TURBULENCE AND MIXING VIA KELVIN-HELMHOLTZ INSTABILITY TUBE AND KNOT DYNAMICS." The three-year award beginning November 1, 2021 will fund basic research into atmospheric dynamics and turbulence under the NSF's Geosciences program (CFDA 47.050)....

This $276,182 Project Grant awarded by the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) aims to develop a new tool for accurately observing coastal winds using high-frequency (HF) radar. The overall objective is to produce reliable wind observations at the same resolutions as ocean currents, advancing the understanding of coupled ocean-atmosphere dynamics. The funded research will finalize a "tomographic" approach to wind extraction from HF radar signals, which...

The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $453,861 Project Grant to the University of Pittsburgh to support research titled "Turbulence in the Long-Lived, Very Stable Atmospheric Boundary Layer." The award period is from June 1, 2022 to May 31, 2025. The grant funds research aimed at better understanding turbulence under stable atmospheric conditions, such as those frequently observed at night or during cold seasons, and developing reliable...

This National Science Foundation (NSF) Geosciences program Project Grant award, with a total funding of $438,734, supports a collaborative research effort to study the turbulence in the stratified layer at the air-water interface caused by waves and wind. The research will be conducted through a combination of controlled laboratory experiments and state-of-the-art numerical simulations, with the goal of improving the representation of the ocean surface boundary layer in Earth-system models....

This Cooperative Agreement award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $701,417 to support the inclusion of the Multi-function Airborne Raman Lidar (MARLI) and Airborne Doppler Lidar (ADL) instruments into the Community Instruments and Facilities (CIF) program. These lidar systems, when operated together, can simultaneously measure water vapor, temperature, wind, aerosols, and cloud profiles within the planetary boundary layer. This award will...
