“This article introduces the research progress in the field of lake land cloud cover differences. Based on Sentinel-5P cloud cover data from 2019 to 2023 and combined with ERA5 and ERA5 Land reanalysis data, relevant experts analyzed the spatiotemporal pattern, influencing factors, and physical processes of cloud cover differences in 334 lakes and their adjacent land in China during summer and autumn seasons, providing important basis for the study of lake land radiation differences and the selection of lake model driven data.”
