青藏高原五大河源区冰川径流数据集（1971-2015）

青藏高原五大河源区冰川径流数据集覆盖时间从1971年到2015年, 时间分辨率为逐年，覆盖范围为青藏高原五条大江大河源区(黄河源，长江源，澜沧江源，怒江源，雅鲁藏布江源)。 数据以多源遥感和实测数据为基础，使用青藏高原五大河源区及其周边气象站点日尺度气象数据、UMD-1KM的全球植被产品、IGBP-DIS土壤数据库、第一、二次冰川编目数据等驱动模型，耦合了冰川模块的分布式水文模型VIC-CAS模拟形成了冰川径流数据。并使用站点实测数据对模拟结果进行了验证, 增强质量控制。 数据指标包含：冰川径流率（Rate of glacier runoff: %），总径流（Total Runoff，mm/a），雪径流率（Rate of snow runoff: %），降雨径流率 （降雨径流率:%）。The glacier runoff dataset for the five source regions of the Qinghai-Tibet Plateau spans from 1971 to 2015, with an annual temporal resolution. It covers the source regions of five major rivers on the Qinghai-Tibet Plateau: the Yellow River Source, Yangtze River Source, Lancang River Source, Nu River Source, and Yarlung Zangbo River Source. This dataset is developed based on multi-source remote sensing and in-situ measured data. Daily meteorological data from meteorological stations within and surrounding the five source regions of the Qinghai-Tibet Plateau, the UMD-1KM global vegetation product, the IGBP-DIS soil database, and the first and second glacier inventory datasets are used to drive the model. The glacier runoff data is generated via simulations conducted with the VIC-CAS distributed hydrological model coupled with a glacier module. The simulation results were validated using in-situ measured data to enhance quality control. The dataset indicators include: glacier runoff rate (Rate of glacier runoff: %), total runoff (Total Runoff, mm/a), snow runoff rate (Rate of snow runoff: %), and rainfall runoff rate (Rainfall runoff rate: %).
