Project Grant FA86552210001

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $359,725 to the University of Texas at Dallas to explore the variability of the interhemispheric asymmetry (IHA) of the equatorial ionization anomaly (EIA) in the American sector across different solar cycles and unravel the mechanisms driving significant IHA of the post-sunset EIA. The research aims to enhance the prediction of EIA variations and mitigate the impacts on global...

This three-year, $406,141 National Science Foundation Project Grant through the Geosciences program (CFDA 47.050) supports research examining the vertical structures of ionosphere-atmosphere coupling using decadal observations and ionospheric models. Key products include analyses of reanalysis data and satellite observations from the past two decades to derive vertical electron density structures related to the solar cycle, quasi-biennial oscillation, El Niño-Southern Oscillation, and Pacific...

The National Science Foundation's Geosciences Program (CFDA 47.050) awarded a $291,289 project grant to Clemson University on Aug 15, 2025 for the collaborative research project "Subauroral Atmospheric and Ionospheric Dynamics at the Edge of Space". This project will investigate natural irregularities in the Earth's ionosphere at altitudes of about 100 km that affect radio wave propagation and space-based operational systems. The research will use radars, GNSS receivers, and other...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $210,153 to Embry-Riddle Aeronautical University to conduct collaborative research on the ionospheric density response to solar eclipses across the United States. The research project aims to quantify the impact of solar eclipses on the ionosphere, a crucial region of the atmosphere that affects radio communication and navigation, and to identify the key factors driving these ionospheric...

The National Science Foundation's Geosciences Program (CFDA 47.050) has awarded a $333,016 Project Grant to Andrews University in Berrien Springs, Michigan. This 3-year collaborative research project, titled "CEDAR--Effects of Ionospheric Density Irregularities on High-Frequency Radio Wave Propagation," aims to investigate the impact of ionospheric density fluctuations on the propagation of high-frequency (HF) radio waves. The research will utilize satellite data, HF amateur radio...

This National Science Foundation Project Grant of $523,833 will fund research into impacts of atmospheric waves and geomagnetic disturbances on space weather through April 2025. Under the Geosciences program (CFDA 47.050), which supports basic research to increase understanding of the integrated Earth system, the awardee Clemson University will collaborate with Embry-Riddle Aeronautical University, Massachusetts Institute of Technology, New Jersey Institute of Technology, and Virginia...

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,...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will establish a distributed network of meteor radars and optical instruments in the mid-latitudes of South America. The $361,050 project, awarded to SRI International, will provide continuous measurements of upper atmospheric winds and nighttime wave perturbations in the mesosphere and thermosphere. The network will enable multi-point observations to analyze the detailed 4-dimensional structures of...

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...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $166,193 to The Johns Hopkins University to conduct collaborative research on the ionospheric density response to solar eclipses across the United States. The primary objectives are to: 1) quantify how solar eclipses impact the ionosphere's electron density and variations in the F-region height, and 2) identify the key factors driving these ionospheric responses, including reduced solar...
