River ice cover dataset of Erqis River Basin (2004-2005) v1.0

River ice is the main component of the cryosphere, and the freezing of rivers in the polar region has a significant impact on the Arctic shipping and transportation industry. With the construction of "ice silk road" between China and Russia, monitoring the change of river ice in Erqis river basin can provide theoretical basis for river navigation. The sparse distribution of hydrological stations in the Arctic limits the study of river ice. The limited available data of hydrological stations show that the trend of river ice rupture is ahead of schedule, but the specific climate mechanism driving this trend is very complex. Therefore, optical data with high temporal resolution (such as MODIS products) are suitable for monitoring river ice phenology and mapping river ice cover range, which is helpful to understand the process of river ice rupture. Based on MODIS and passive microwave data, a method of monitoring river ice in Erqis River Basin by using different remote sensing data is realized in this study, in order to analyze the phenological parameters of river ice such as the time of river closure, the time of river closure, the speed of river opening, the speed of river closure and the duration of freezing period. At the same time, it is helpful to understand the response of river ice breaking process to Arctic climate warming.

File naming and required software

File name: river ice data is stored in TIF format. The file name is "5D ﹣ moyd ﹣ DD ﹣ CJ. TIF", where yyyy represents the year and DDD represents the date. For example, 5D ﹣ moyd ﹣ 2004005 ﹣ CJ. TIF represents this TIF file to describe the consolidated coverage of Erqis River Basin on the fifth day of 2004. Data reading mode: all TIF files in the dataset can be opened with ArcGIS.
