【#Tech24H】For a long time, technical limitations have hindered researchers from conducting detailed monitoring of soil freeze-thaw processes on a global scale. Scientists from the Aerospace Information Research Institute under the Chinese Academy of Sciences and Beijing Normal University have successfully created and released a global high-precision long time series soil freeze-thaw dataset. This dataset acts like a detailed “physical examination” of the Earth’s surface, achieving continuous and detailed observation of freeze-thaw processes globally, particularly over the Tibetan Plateau, for the first time. It provides critical scientific data for addressing climate change and assessing water resource variations. The released dataset establishes a comprehensive historical record of freeze-thaw changes on the Tibetan Plateau over nearly half a century.
