Analysis on Global Es Layer Response to the May 2024 Geomagnetic Storm Through a Combination of Tianmu‐1 and COSMIC‐2 Radio Occultation Observations

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The sporadic E (Es) layer, a key manifestation of ionosphere‐neutral atmosphere coupling, is highly sensitive to geomagnetic storms. Using more than 25,000 daily radio occultation profiles from the Tianmu‐1 and COSMIC‐2 constellations, this study investigates the global response of the Es layer to the May 2024 storm.

Capturing Extreme Water Vapor and Instability With High‐Resolution GNSS Monitoring

Atmospheric Science Letters, Volume 27, Issue 2, February 2026.
This study used data from a high‐resolution Global Navigation Satellite System network (< 10 km spacing), including private stations, to analyze water vapor structure during a heavy rainfall event in Japan. The network captured localized extreme precipitable water vapor (> 70 mm) and a moist absolutely unstable layer near the humid core.
