Lake ice experiment of in situ and remote sensing observation in Wuliangsuhai Lack, China

Wuliangsuhai Lake is the largest lake in the basin of Yellow River, and is a very important irrigation and drainage system in the Hetao Irrigation Area. In the winter of 2019, we collected satellite observation synchronously including Gaofen-1 optical data, sentinel-1 C band SAR and AMSR2 brightness temperature (TerrSAR-X and Gaofen-3 SAR-C are also collected but not showed here ), unmanned aerial vehicle (UAV) ice image; and in situ observation including lake ice temperature, ice thickness and meteorological data.
