- This $517,046 Project Grant award from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) supports collaborative research on plasma turbulence and heating in the solar chromosphere. The investigators will carry out theoretical analysis and computer simulations to test the hypothesis that small-scale plasma processes, known as the thermal Farley-Buneman instability, cause heating in the coolest parts of the Sun's atmosphere. The research team will use observational data...
- This $429,227 Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), will support a collaborative research project to resolve uncertainty in past carbon-14 (Δ14C) spikes from tree rings. The goal is to better understand past solar energetic particle events, which pose risks to space-based infrastructure, by quantifying physiological sources of uncertainty in Δ14C measurements from tree rings. The project will use field and model-based experiments to...
- This $135,000 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) supports collaborative research to study the impact of solar eclipses on the ionosphere, a critical region of Earth's atmosphere that affects radio communications and navigation. The lead awardee, the Regents of the University of Colorado (a U.S. state government entity and institution of higher learning), will coordinate multi-instrument observations of ionospheric parameters during...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) grant award provides $593,864 to the New Jersey Institute of Technology (NJIT) from September 2024 to August 2027. The project will develop an AI-driven framework called SolarDM to generate high-resolution, high-cadence vector magnetograms of the solar chromosphere and photosphere. These AI-generated products will provide valuable data on the Sun's magnetic field to significantly advance the understanding and prediction...
- The National Science Foundation awarded a $565,903 project grant to the University of Colorado Boulder under the Mathematical and Physical Sciences program (CFDA 47.049) to support research examining the role of acoustic waves in the solar chromosphere. Through simulations using two 3D radiative magnetohydrodynamic codes, the awardee will study how acoustic wave excitation events and atmospheric preconditioning impact the thermodynamics and ionization state of the chromosphere. Results will be...
- Federal Project Grant Award Summary The National Science Foundation's Division of Atmospheric and Geospace Sciences has awarded $202,000 through the Geosciences program (CFDA 47.050) to support a postdoctoral research fellowship project beginning September 1, 2025, and concluding August 31, 2027. The award funds research focused on quantifying solar wind input uncertainty in global geospace models through perturbed input ensemble modeling. The primary deliverables include: (1) quantified...
This National Science Foundation Project Grant award of $150,674 supports research into understanding variations in solar magnetic activity and their influence on space weather and climate. Funded under the Geosciences program (CFDA 47.050), the award will support an early career researcher at the University of Colorado Boulder from February 2023 through January 2026. The research will address questions related to grand solar minima periods of low activity, how solar behavior changes during these periods, and whether such changes can be modeled or predicted. Using observations of sunspot numbers, isotope records, machine learning techniques and numerical modeling, the researcher aims to reconstruct annual sunspot numbers over the past 11,000 years to better characterize cycle length before, during and after past grand minima. The results seek to improve understanding of grand minima/maxima occurrence and constraints on solar dynamo models to decipher underlying mechanisms driving observed variations in solar activity critical to space weather and climate.
