This $119,927 federal Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) supports research investigating the effects of ionospheric density irregularities on high-frequency (HF) radio wave propagation. The research aims to improve understanding of ground-based HF communications, which are critical for long-distance communications, emergency situations, and various civilian and military applications. The project will utilize satellite data, HF...
This federal Project Grant award of $141,789, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research into the effects of ionospheric density irregularities on high-frequency (HF) radio wave propagation. The project, led by researchers at The Johns Hopkins University, aims to investigate how solar and geomagnetic activities influence ground-based HF communications, analyze small-scale density irregularities in the ionosphere, and evaluate how HF waves...
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 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $555,251 to Andrews University to conduct collaborative research on the propagation and dissipation of electromagnetic ion cyclotron (EMIC) waves in the Earth's magnetosphere and ionosphere. The project aims to address four key scientific questions about how EMIC waves reach the ground, how they are affected by geomagnetic activity, how magnetic field topology impacts wave propagation,...
This National Science Foundation Project Grant of $224,954 will fund research to measure daily ionospheric variability and solar eclipse impacts using amateur radio HF Doppler shift receivers. Over the two-year period from January 2023 to December 2025, the awardee Case Western Reserve University will collaborate with the Hamsci amateur radio community on a project called CEDAR. Thirty Hamsci GRAPE receivers will be deployed across North America to study ionospheric responses to dawn, dusk,...
This Project Grant award for $210,124, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), will enable the deployment and operation of the Ham Radio Science Citizen Investigation (HAMSCI) Personal Space Weather Station Network. The project will install thirty standardized HAMSCI stations across the U.S. and Canada to observe high-frequency Doppler shifts, amateur radio transmissions, very low-frequency signals, and geomagnetic fields. The network will also deploy ten...
This Project Grant award of $180,225 from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund the "Collaborative Research: DASI Track 2: Deployment and Operations of the Ham Radio Science Citizen Investigation (HAMSCI) Personal Space Weather Station Network" at the New Jersey Institute of Technology (NJIT). The project aims to deploy a network of thirty standardized space weather monitoring stations and ten automated GPS-disciplined amateur radio...
This $165,476 federal Project Grant award was provided by the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of Alabama. The funding will support the deployment and operation of the Ham Radio Science Citizen Investigation (HAMSCI) Personal Space Weather Station Network, a distributed array of small instruments designed to study space weather impacts. The project will deploy 30 standardized stations capable of observing high-frequency Doppler shifts, amateur...
Andrews University was awarded a $385,656 project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences to conduct collaborative research titled "COLLABORATIVE RESEARCH: GEM--RADIATION BELT LOSSES USING COMBINED GLOBAL HYBRID AND TEST PARTICLE SIMULATIONS." The research will be performed from August 1, 2021 through July 31, 2025. The project aims to strengthen understanding of the integrated Earth system through basic research in the atmospheric,...
This National Science Foundation (NSF) Project Grant, funded under the Geosciences program (CFDA 47.050), supports a collaborative research effort to study the ionospheric density response to upcoming solar eclipses in the United States. The $210,153 award to Embry-Riddle Aeronautical University, effective October 1, 2024, aims to quantify the impacts of reduced solar flux on the ionosphere during the October 2023 and April 2024 solar eclipses. The project will leverage ground-based radio...
