- The National Science Foundation (NSF) Geosciences program (CFDA 47.050) has awarded a $194,361 collaborative research project grant to the University of Illinois, the University of California, Berkeley, and SRI International. The five-year project, "An Observational Network to Enable Investigations of Gravity-Wave and Storm-Time Impacts on the Mid-Latitude Thermosphere-Ionosphere," aims to operate and maintain the existing Mid-Latitude All-Sky-Imaging Network for Geophysical...
- This $272,363 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research effort at Aerodyne Research Inc. to better understand the formation and yields of key secondary atmospheric species, such as ozone, formaldehyde, and secondary organic aerosol, resulting from the oxidation of non-methane volatile organic compounds. The research will involve model-informed chamber studies to carefully control and monitor the reactivity of...
- This $359,936 Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a three-year observational program to measure winds and temperatures in the thermosphere near the ionospheric peak density from multiple sites along the eastern seaboard of the Americas. The project uses a network of Fabry-Perot interferometers to provide high-precision, real-time data on thermospheric dynamics and conditions that impact critical communication, navigation,...
- The National Science Foundation (NSF) awarded a $201,941 Project Grant under its Geosciences Program (CFDA 47.050) to Clemson University. The grant, titled "COLLABORATIVE RESEARCH: GEM: THE ELECTRODYNAMIC PROPERTIES OF MESO-SCALE AURORAL FORMS," aims to determine the characteristic features of meso-scale auroral forms and improve the understanding of multi-scale ionospheric electrodynamics. The project will leverage computer vision techniques to systematically analyze all-sky images...
This $438,685 Project Grant from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by SRI International to study the O2(A-X) infrared atmospheric band nightglow emission in the Earth's upper atmosphere. The goal is to advance the understanding of this important airglow phenomenon, which has not been fully explained despite decades of space-based observations. The research will analyze and model existing data sets on the infrared nightglow emission, with a focus on the potential coupling between the hydroxyl (OH) layer and electronically excited O2(A) species responsible for the emission. This 3-year project, running from August 2025 to July 2028, aims to enable better interpretation of the observed nightglow altitude profiles, which could lead to improved modeling of atmospheric waves and oxygen concentration determination.
