Daily Lake Ice Phenology Time Series Derived from AMSR-E and AMSR2, Version 1

The Daily Lake Ice Phenology Time Series Derived from AMSR-E and AMSR2 provides 5 km ice phenology retrievals describing daily lake ice conditions (ice-on/ice-off) over the Northern Hemisphere. This satellite-based data set allows for rapid assessment and regional monitoring of seasonal ice coverage over large lakes with resulting accuracy suitable for global change studies. Data are provided in the 5 km Northern Hemisphere Equal-Area Scalable Earth Grid 2.0 (EASE-Grid 2.0).基于先进微波扫描辐射计地球观测系统（AMSR-E）与先进微波扫描辐射计2号（AMSR2）生成的每日湖泊冰物候时间序列数据集，提供分辨率为5公里的冰物候反演结果，用以描述北半球范围内湖泊的每日冰情状态（结冰/融冰）。 该卫星数据集可实现大型湖泊季节性冰覆盖范围的快速评估与区域性监测，其反演精度足以支撑全球变化研究。数据采用北半球5公里分辨率的等面积可缩放地球网格2.0（EASE-Grid 2.0）格式提供。
