Bridging the Gap Between the Earth's Ionosphere and Plasmasphere

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Cold plasma distribution in the ionosphere‐plasmasphere system governs wave‐particle interactions, plasma energization and loss, and radio wave propagation. A longstanding observational gap at altitudes ∼ ${\sim} $800–8,000 km has largely prevented studying the coupled dynamics of the two regions.

Impact of Filtering Methods in the Assessment of COSMIC Electron Density Profiles Over the Brazilian Region: Excluding Profiles With Negative Values Is the Best Strategy?

Radio Science, Volume 60, Issue 11, November 2025.
Abstract Global Navigation Satellite Systems radio occultation (RO) is a valuable and relevant source of information from the atmosphere. Many efforts have been made to provide methods of validation of RO profiles, however, no clear methodology for filtering the profiles from RO can be easily found.

Thermospheric Density Disturbances During the 2015 St. Patrick's Day Geomagnetic Storm: Model–Observation Comparisons and Analysis of Intense Polar Density Spikes

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Drag affecting satellites in low Earth orbit varies significantly during geomagnetic storms due to changes in thermospheric density. While neutral density can be inferred from satellite measurements, such data sets are limited and restrict neutral density/orbit prediction capabilities.

Thermospheric Density, Composition, and Temperature From GOES‐R/SUVI Solar Occultations

Space Weather, Volume 23, Issue 9, September 2025.
Abstract A new data set of atomic oxygen (O) and molecular nitrogen (N2 ${\mathrm{N}}_{2}$) number density profiles, along with thermospheric temperature profiles between 180 and 500 km, has been developed. These profiles are derived from solar occultation measurements made by the Solar Ultraviolet Imager (SUVI) on the GOES‐R satellites, using the 17.1,

A Tetranucleotide Repeat Mouse Minisatellite Displaying Substantial Somatic Instability during Early Preimplantation Development

Genomics, 1993
The highly variable mouse minisatellite Hm-2 is located on chromosome 9 and consists of GGCA tetranucleotide repeats with alleles containing up to 5000 repeat units. This locus is unstable with a germline mutation rate to new length alleles of at least 3.6% per gamete.
