In the context of current global climate change, the study of key processes and parameters of polar regions is a key area of global change research, and is crucial to reveal the influence of polar ice sheets on global sea level change and improve the prediction accuracy of sea level rise contribution. Polar scientific expeditions can provide in situ data sets that could be used in calibration and validation of remote sensing observations and reduce the uncertainty of remote sensing inversions. Based on the remote sensing and fieldwork of the global change research team of Tongji University on key parameters of the polar ice sheet, this paper focuses on the team's research on the validation of polar scientific research observations and data processing, including the satellite-ground synoptic validation of altimetric satellites on the Antarctic ice sheet, the deployment of satellite angular reflectors, the observation and model validation of the internal temperature of the granular snow layer, the multi-platform UAV (unmanned aerial vehicle) sea ice detection and snow-ice environment investigation, and mass change assessment of the Greenland Ice Sheet, etc. Finally, an outlook on the future polar science research validation program is provided.
