This data set provides the lake ice phenology of 71 lakes on the Qinghai Tibet Plateau from 2001 to 2020, including the freeze-up start, freeze-up end, break-up start, break-up end, complete freezing duration, and ice cover duration. The data set was extracted from the cloud-gap-filled MODIS daily snow product based on a dynamic changed threshold. Compared with the coarse resolution passive microwave AMSR-E/2 lake ice phenology data set, the average absolute error of the freeze-up start date was 2.33-7.25 days, and the average absolute error of the break-up end date was 1.75-4.67 days. The data can provide a data basis for the relevant research on the response of the Qinghai Tibet Plateau lake system to climate change.

File naming and required software

File name: lake ice phenology data is stored in csv format, and the file name is "lake_name. csv", where lake_name represents the English name of each lake. For example, Qinghai Lake.csv represents this csv file to describe the lake ice phenology records of Qinghai Lake from 2001 to 2020.
Data reading mode: all csv files in the dataset can be directly opened with Excel and other software.
