TY - Data T1 - 30m Permafrost Depth Map of Kamalan River Basin in Dongpo Tahe Area of Daxing'anling Mountains (2023-2025) A1 - Zang Shuying DO - 10.12072/ncdc.nieer.db7244.2026 PY - 2026 DA - 2026-03-31 PB - National Cryosphere Desert Data Center AB - This dataset is the burial depth data of permafrost in the Kamalan River Basin in the Dongpo Tahe area of the Greater Khingan Range. Based on the surface temperature (GST) of 14 HOBO monitoring stations in the study area, a regression model of "surface temperature environmental factors" was constructed to calculate the melting index. Calculate the E factor using the classification assignment method. Using the Stefan model, simulate the thickness of the active layer of permafrost in typical areas. The simulation result has an R2 of 0.64 and an RMSE of 0.41 m. The data format is GeoTIFF, with a spatial resolution of approximately 30 meters and a projection of WGS1984_ Albers.
