- This $594,429 federal Project Grant was awarded on July 1, 2024 by the National Science Foundation's Geosciences program (CFDA 47.050) to The Johns Hopkins University in Laurel, Maryland. The grant will fund research to investigate the structure, stability, and reconnection regimes of "overstretched" current sheets in the Earth's magnetotail in order to understand the mechanism of reconnection onset and its global implications for modeling and predicting space weather phenomena. The...
- The National Science Foundation Office of Integrative Activities awarded The Johns Hopkins University $2.28 million on August 15, 2026, under the Geosciences program (CFDA 47.050) to extend and improve the Active Magnetosphere and Planetary Electrodynamics Response Experiment 4 (AMPERE-4), a collaborative research infrastructure project focused on analyzing magnetic data from commercial spacecraft to study the aurora borealis and Earth's magnetosphere. AMPERE-4 purchases magnetometer data from...
- This Project Grant award of $256,279, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), aims to characterize quiet-time equatorial plasma bubbles and their impact on radio signal scintillation. The primary objectives are to investigate the driving mechanisms behind these plasma bubbles, their longitudinal, day-to-day, and seasonal variations, and the specific parameters controlling their dynamics and lifetime, as well as the resulting scintillation effects. The...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded $450,830 to the Regents of the University of California, doing business as University of California, Berkeley, on August 15, 2026, under the Geosciences program (CFDA 47.050) to characterize cold plasma density fluctuations in Earth's inner magnetosphere and improve space weather prediction capability. The project will quantify amplitudes, temporal characteristics, spatial structure, and relationships to...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $224,797 Project Grant to The Johns Hopkins University from June 1, 2021 to May 31, 2024. The grant supports collaborative research titled "Effects of Thermospheric Winds on Equatorial Spread-F" under the Geosciences program (CFDA 47.050). The Geosciences program aims to expand fundamental knowledge of Earth's integrated system through basic atmospheric, earth, and ocean sciences research. This...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded The Regents of the University of Colorado $346,253 on August 1, 2026, through the Geosciences program (CFDA 47.050) to develop improved methods for measuring low-frequency whistler-mode hiss waves in Earth's magnetosphere. The project will implement a new methodology to measure wave amplitude and frequency distributions while circumventing instrumental noise limitations that have constrained prior analysis....
The National Science Foundation Office of Integrative Activities awarded The Johns Hopkins University $443,609 on August 1, 2026 under the Geosciences program (CFDA 47.050) to characterize the magnetic signatures of equatorial plasma bubbles and their connection to GPS navigation degradation. The recipient will produce the first comprehensive statistical characterization of magnetic signatures in equatorial plasma bubbles, exploiting simultaneous magnetic field, plasma density, and GPS observations from European and American satellites during high solar activity periods. The work addresses three primary science questions: the dominant sources of magnetic perturbations in these bubbles and their variation with morphology, altitude, and ambient conditions; how signatures vary with local time, season, longitude, and solar activity; and whether magnetic observations can serve as a quantitative proxy for forecasting space weather impacts. The research draws on twelve years of satellite measurements to develop methodology for improving lead time and regional precision of space-weather forecasts that protect navigation-dependent infrastructure. The project also supports development of an early-career scientist. Place of performance is Laurel, Maryland. The period of performance runs from August 1, 2026 through July 31, 2029.
