全球冰冻圈范围及物候数据集（1979-2016）

在全球气候变暖背景下，冰冻圈是气候变化最敏感圈层之一。冰冻圈是世界上最大的淡水资源库。冰冻圈的变化对于地气系统能量交换、水资源、生态、灾害过程等产生重要影响。所以探究冰冻圈变化对于气候变化响应显得尤为重要。利用卫星遥感资料、再分析数据、观测资料，集合冰冻圈各要素于一体，构建了1979-2016年全球尺度冰冻圈范围及物候数据集。其结果可以用于进一步冰冻圈对气候变化响应机制研究，以及对于生态系统、碳循环等研究提供基础支撑。

Against the backdrop of global warming, the cryosphere is one of the most sensitive spheres to climate change. The cryosphere is the world's largest freshwater reservoir. Changes in the cryosphere exert significant impacts on energy exchange in the earth-atmosphere system, water resources, ecosystems, disaster processes and other related aspects. Therefore, it is particularly important to explore the response of cryospheric changes to climate change. Using satellite remote sensing data, reanalysis data and observational data, and integrating all components of the cryosphere, we have constructed a global-scale cryospheric extent and phenology dataset covering the period from 1979 to 2016. This dataset can be used to further investigate the response mechanisms of the cryosphere to climate change, and provide fundamental support for research on ecosystems, the carbon cycle and other relevant fields.
