2020-2022年北半球高纬地区中分辨率MODIS河湖冰物候数据集

2019-2022年北半球高纬度中分辨率MODIS河湖冰物候数据集，是基于MODIS归一化差分积雪指数（NDSI）数据产品提取的，数据包括欧亚大陆流向北冰洋的六大流域的逐日河冰覆盖范围、河冰覆盖度与河冰物候数据和欧亚大陆会发生冻结现象的湖泊的逐日湖冰覆盖度。河湖冰覆盖范围数据格式为tif，投影为WGS-84。河湖冰覆盖度与河湖冰物候数据格式为excel。The Medium-resolution MODIS River and Lake Ice Phenology Dataset for High-latitude Northern Hemisphere (2019–2022) was derived from the MODIS Normalized Difference Snow Index (NDSI) data product. This dataset includes daily river ice extent, river ice cover fraction and river ice phenology data for six major river basins in Eurasia that drain into the Arctic Ocean, as well as daily lake ice cover fraction data for seasonally frozen lakes across Eurasia. The river and lake ice extent data is stored in tif format and projected in WGS-84. The river and lake ice cover fraction and river ice phenology data are formatted as Excel files.
