Performance Evaluation of Satellite Observation of Sand/Dust Weather and Its Application in Assessing the Accuracy of Numerical Models

Applied Sciences
Air quality monitoring and forecasting has been a challenging problem for years. In addition to traditional ground-based observational stations, in recent years there have been more geostationary and polar orbiting satellite observations on air quality ...

Surface Air Enrichment of Cosmogenic 35S at a Subtropical Site During the May 2024 Solar Superstorm

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Cosmogenic radiosulfur (35S) is produced in the atmosphere by high‐energy particle interactions and serves as a sensitive tracer of stratospheric intrusions. In May 2024, an extreme solar storm provided a rare opportunity to examine atmospheric 35S responses to intense solar activity.

CNN‐Based Retrieval of 3D Cloud Structures Solely From Geostationary Satellite Imagery

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The cloud vertical structure (CVS) is important, yet operational CVS products depend on active observation or reanalysis fields, limiting high‐frequency monitoring. In this study, we propose a lightweight and satellite‐only model that reconstructs volumetric cloud masks from geostationary multispectral imagery.

Deep-Learning-Based Multi-Channel Satellite Precipitation Forecasting Enhanced by Cloud Phase Classification

Remote Sensing
Clouds are closely related to precipitation, as their type, microphysical characteristics, and dynamic properties determine the intensity, duration, and form of rainfall. While geostationary satellites offer continuous cloud-top observations, they cannot

Characterization and Localization of Chemical Explosions and Lightning Flashes by a Flotilla of Stratospheric Balloons

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract On 3 August 2021, a flotilla of four Heliotrope solar hot air balloons was launched from central New Mexico (USA). The balloons, equipped with microbarometers, flew from sunrise to sunset at altitudes between 17 and 22 km. During the flight, eight chemical explosions ranging from 45 to 136 kg TNT equivalent and a thunderstorm occurred in the ...
