1990-2018年干城章嘉流域冰川物质平衡序列模拟数据集
A dataset of simulated sequences of glacier mass balance in the Kanchenjunga Basin during 1990-2018
摘要
Abstract
As a result of climate change,the global glacier shrinkage was observed,and glaciers of different types have experienced distinct changes in their mass budgets.Debris-covered and/or lake-terminating glaciers have been identified in the Kanchenjunga Basin,and the dataset of their mass balance on a long-term scale could provide an important basic data for studies of specific responses of glaciers of various types to climate change.Using the rectified China Meteorological Forcing Dataset,we reconstructed the daily mass balance of glaciers in the Kanchenjunga Basin from 1990 to 2018 through the application of a surface energy balance model.We used a glacier elevation change dataset obtained through geodetic methods to validate the model estimation results,and the results align closely with previously published research results on a multi-year scale.We extracted the surface velocities of glaciers from 1989 to 2018 from the ITS_LIVE dataset and assessed their precision based on the statistical characteristics of the surface movements in the glacier-free regions.This dataset is expected to provide basic data for the studies of the responses of glaciers with different types to climate change,and can also offer valuable references for the studies of glacial hydrological effects and disasters.关键词
