Project Grant FA23861414089

This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $359,725 to the University of Texas at Dallas (UTD) aims to enhance understanding of the variability and characteristics of the equatorial ionization anomaly (EIA) in the American sector across different solar cycles. The research methodology involves analyzing total electron content (TEC) data from ground-based GNSS receivers and employing NCAR TIEGCM simulations to unravel the mechanisms driving...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to investigate the evolution of the global total electron content (TEC) during solar flares. The $112,514 award to the University of Texas at Arlington (UTA) aims to improve understanding and predictability of how solar flares impact the upper atmosphere and affect critical communication and navigation systems. The research team plans to analyze global TEC data from...

This award for $108,120 from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research project led by The Aerospace Corporation to characterize quiet-time equatorial plasma bubbles and their impact on radio signal scintillation. The project aims to improve understanding of the drivers and evolution of these plasma disturbances, which can disrupt communications and navigation systems relied upon by various government and commercial entities. The...

This $174,257 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund collaborative research to measure daily ionospheric variability and solar eclipse impacts using amateur radio HF Doppler shift receivers. Led by the University of Scranton, the project will deploy thirty GRAPE receivers across North America to study ionospheric responses to dawn, dusk, and solar eclipses in 2023 and 2024. The receivers will generate observations to answer scientific...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $416,131 to the University of Texas at Dallas (UTD) to develop an advanced, low-cost ionospheric scintillation and total electron content (TEC) monitor for studying the near-Earth plasma environment. The project aims to create a distributed array of small instruments capable of high-resolution measurements comparable to commercial monitors, but at a fraction of the cost. The advanced...

This $212,120 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) funds research into the impacts of atmospheric waves and geomagnetic disturbances on space weather conditions. Led by the Massachusetts Institute of Technology in collaboration with Clemson University, Embry-Riddle Aeronautical University, New Jersey Institute of Technology, and Virginia Polytechnic Institute and State University from May 1, 2022 to April 30, 2025, the research will advance...

The University of Texas at Austin received a three-year, $867,805 Project Grant from the Department of the Navy to measure three-dimensional propagation effects at the Atlantis II Seamount Complex during the Transoceanic Fluctuation Observatory pilot experiment. Funded under the Basic and Applied Scientific Research program (CFDA 12.300), the grant will support applied research at the university's Applied Research Laboratories from June 2021 to May 2024. The program aims to stimulate basic and...

The Department of the Navy's Office of Naval Research awarded a $399,654 Project Grant under the Basic and Applied Scientific Research program (CFDA 12.300) to SRI International to conduct research on "Equatorial Spread-F (ESF) Weather: Day-to-Day Variability". The project will investigate the day-to-day fluctuations in the equatorial ionosphere, which can disrupt satellite communications and navigation signals. SRI International will lead the research effort, with support from...

The National Science Foundation (NSF) awarded a $141,789 Project Grant under the Geosciences program (CFDA 47.050) to The Johns Hopkins University to investigate the effects of ionospheric density irregularities on high-frequency (HF) radio wave propagation. The 3-year research project aims to improve understanding of how space weather and small-scale density fluctuations in the ionosphere impact ground-based HF communications used for long-distance applications like international...

This $256,279 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to characterize and investigate the driving mechanisms behind quiet-time equatorial plasma bubbles (EPBs) that induce scintillation on radio signals. The research will leverage data from various instruments, including GNSS receivers, LEO satellites, ionosondes, and UV imagers, to address fundamental questions about the underlying drivers of EPBs during magnetically quiet periods and...
