We developed "FYAI" (Fengyun Satellite-Based Dataset for Atmospheric Ice Water Path), a fifteen-year dataset (2010–2024) derived from Chinese Fengyun satellites. Using artificial intelligence, we mapped global atmospheric ice. This continuous record fills critical gaps in observation. It provides scientists with a vital tool to improve weather forecasts and better understand how atmospheric ice interacts with the global climate system.

Ozone pollution is a growing issue in China, with levels increasing steadily from 2020 to 2024. This study uses satellite data to explore how different pollutants interact to form ozone. The results show that urban areas shift their pollution control strategies throughout the day. These findings suggest that targeting specific pollutants at different times could significantly improve air quality and help reduce harmful ozone pollution in China.

Our research improves satellite-based precipitation monitoring by using deep learning to reconstruct radar observations from passive microwave radiances. Active radar is costly, so we focus on a more accessible approach. Using data from the Fengyun-3G satellite, we successfully tracked severe weather like Typhoon Khanun and heavy rainfall in Beijing in 2023. This method enhances global precipitation data and helps better understand extreme weather.

This paper proposes a novel methodology for selecting sulfur-dioxide-sensitive channels from FY-3E/HIRAS-II hyperspectral IR atmospheric sensors to quantitatively monitor volcanic sulfur dioxide. This methodology considers the interference of atmospheric temperature, humidity, and surface temperature with sulfur dioxide detection and retrieval, laying the groundwork for developing a more accurate and flexible volcanic sulfur dioxide retrieval algorithm under different atmospheric conditions.

The Japanese Himawari-8 and Himawari-9 (H8/9) geostationary (GEO) satellites are strategically positioned over the South China Sea (SCS), spanning from 3 November 2022 to the present. They mainly provide cloud mask, fraction, height, phase, optical, and microphysical property; layered precipitable water; and sea surface temperature products within a temporal resolution of 10 min and a gridded resolution of 0.05° × 0.05°.

Based on the MicroWave Radiation Imager aboard FY-3 series satellites, we developed a global terrestrial precipitable water vapor dataset from 2012 to 2020. This dataset overcomes the limitations of infrared observations and provides accurate, all-weather PWV data ,spanning all types of land surface. Researchers are expected to leverage it to explore the role of water vapor in weather patterns, refine precipitation forecasting, and validate climate simulations.

Short summary
Our study primarily addresses the feasibility of employing advanced machine learning and physics-based algorithms to capture the diurnal variations in cloud base height parameters using geostationary meteorological satellite remote sensing. The results indicated that the caution is warranted when utilizing cloud base property products trained on satellite and laser radar data for climate research. Fixed training samples might obscure the pronounced diurnal variations in cloud base heights.

A typhoon is a high-impact atmospheric phenomenon that causes most significant socioeconomic damage, and its precipitation observation is always needed for typhoon characteristics and disaster prevention. This study developed a typhoon precipitation fusion method to combine observations from satellite radiometers, rain gauges and reanalysis to provide much improved typhoon precipitation datasets.

Short summary
We developed a three-dimensional wind dataset for the Yangtze River Delta with hourly information at one-kilometer resolution for the summers from 2021 to 2023. Using atmospheric modeling combined with ground observations and land surface data, the dataset represents local wind behavior more accurately than existing products. It supports studies of extreme weather, air pollution transport, wind energy planning, and low-altitude airspace safety in rapidly urbanizing regions.
