Preservation of Historically and Scientifically Important Geospatial Data From Venus

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Impacts of Atmospheric Rivers in Central Greenland: Snowfall, Clouds, and Atmospheric State

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Atmospheric rivers (ARs) are long bands of strong horizontal water vapor transport responsible for over 90% of total integrated vapor transport (IVT) in extratropical and polar regions. Using a 12‐year record (2010–2022) of ground‐based remote sensing, radiosonde, snow stake, and reanalysis data from Summit Station, Greenland, we quantify the ...

A Modified Hierarchical Vision Transformer for Soil Moisture Retrieval From CYGNSS Data

open access: yesWater Resources Research, Volume 62, Issue 1, January 2026.
Abstract This research introduces a new deep learning (DL) framework, multi‐head self‐attention‐aided vision Transformer (MSA‐ViT), for soil moisture (SM) retrieval using Cyclone Global Navigation Satellite System (CYGNSS) data. We first assess the sensitivity of CYGNSS reflectivity (Γ) $({\Gamma })$ to SM, demonstrating a strong physical linkage ...
