第三极冰川储量（1994-2008）

数据内容包括第三极地区16个子区域冰川的数量、面积、平均厚度和体积，进而获得整个第三极地区的冰川储量（单位：立方公里）。冰川数量和面积数据来自GAMDAM亚洲冰川编目。基于OGGM平台，采用冰流通量模型、冰川底部应力模型、冰流速模型3类冰厚反演模型，通过不同的模型参数和冰川中心流线方案，扩展出共计15种冰川冰厚反演模型。模拟结果与实测冰厚的平均绝对误差为27.3%。本储量数据是研究冰川水资源和冰川变化的基础。The dataset encompasses the count, area, average thickness and volume of glaciers in 16 sub-regions of the Third Pole region, based on which the total glacier storage (unit: cubic kilometer) of the entire Third Pole region is derived. The glacier count and area data are sourced from the GAMDAM Asian Glacier Inventory. Based on the OGGM platform, three categories of ice thickness inversion models, namely ice flux model, glacier basal stress model and ice flow velocity model, were employed. By varying model parameters and glacier center streamline schemes, a total of 15 glacier ice thickness inversion models were developed. The average absolute error between the simulation results and the measured ice thickness reaches 27.3%. This glacier storage dataset provides a fundamental basis for research on glacial water resources and glacier changes.
