基于ZY-3和SRTM DEM数据的青藏高原山地冰川物质平衡数据产品(2000-2018)

冰川物质平衡指一定时间内冰川上物质积累和消融的代数和，反映了冰川的进退状况，在海平面上升、气候变化、冰川灾害预警及区域水循环等方面有重要作用。联合国产ZY-3和SRTM DEM数据，利用DEM差分及相关误差改正技术，获取了青藏高原山地冰川的物质平衡数据产品(2000-2018)，该数据存储为*.xlsx格式。

Glacier mass balance refers to the algebraic sum of mass accumulation and ablation on glaciers over a given period, which reflects the advance and retreat status of glaciers. It plays an important role in sea level rise, climate change, glacier disaster early warning, regional water cycle and other relevant fields. By combining domestic ZY-3 and SRTM DEM data and adopting DEM differencing and related error correction techniques, a mass balance data product (2000-2018) of mountain glaciers on the Qinghai-Tibet Plateau was obtained, and the data is stored in *.xlsx format.
