The medium-resolution MODIS river and lake ice phenology data set in the high latitudes of the northern hemisphere from 2002 to 2019 is based on the Normalized Difference Snow Index (NDSI) data of the Moderate Resolution Imaging Spectroradiometer(MODIS). Daily lake iceextent and coverage under clear-sky conditions was examined byemploying the conventional SNOWMAP algorithm, and thoseunder cloud cover conditions were re-determined using the temporal and spatial continuity of lake surface conditions througha series of steps.The lake ice phenology information obtained in this dataset was highly consistent with that from passive microwave data at an average correlation coefficient of 0.91 and an RMSE value varying from 0.07 to 0.13.

File naming and required software

The data include the daily lake ice cover of the frozen lakes in Eurasia and the daily river ice coverage in the Irtysh - EBI River Basin. The data of lake ice and river ice are separately stored in the folder of river ice and lake ice. The data format is TIF and the projection is WGS-84. The name of the file is“ yyyyddd.tif ”where yyyy stands for year, ddd stands for Julian date, 2003001.tif is the coverage of lake ice or river ice on January 1, 2003.
