%X This data is based on actual measured sample data of underground ice reserves obtained through mechanical/manual drilling and exploration pits. A random forest regression model is used to conduct spatial prediction modeling with measured volumetric water content (VWC) as the dependent variable and multiple environmental factors as independent variables. The model prediction results are output as grid data for different depth layers (2m above, 2-5m, 5m below), and finally synthesized and produced a map of permafrost underground ice storage at the research area scale. The data format is GeoTIFF, with a spatial resolution of approximately 30m and a projection of WGS1984_ Albers.
