Remote sensing observation, retrieval, and analysis of temperature in the Qinghai-Tibet Plateau cryosphere
The cryosphere serves as a sensitive indicator of climate change, while land surface temperature and near-surface air temperature are signals directly sensed by the indicator. They are key parameters for tracing the evolution history of the cryo-sphere, monitoring the current state, and simulating future changes. Due to a combination of adverse environmental condi-tions, complex terrain, low accessibility, and numerous unique underlying surfaces, ground-based temperature observations are challenging and sparsely distributed in the Qinghai-Tibet Plateau. Remote sensing has become an effective means of tem-perature acquisition. Focusing on land surface temperature and near-surface air temperature, this paper elucidates the related methodologies for ground-based observations, satellite, and unmanned aerial vehicle (UAV) remote sensing retrievals, and summarizes the research progress made by the academic community around the cryosphere of the Qinghai-Tibet Plateau. Fur-thermore, this paper discusses the applications of remote sensing temperature parameters in frozen ground, lake ice, glaciers, and other aspects of the Qinghai-Tibet Plateau. Challenges in temperature remote sensing acquisition in the Qinghai-Tibet Plat-eau cryosphere are summarized, and future research directions worthy of emphasis are explored.
