| Summary: | This dataset contains the Arctic sea ice drift data set in winter and spring (2020)1. This dataset obtains the near real-time Arctic sea ice drift vectors through sentinel-1 SAR image and digital image processing algorithm.2. The time range of this dataset is winter and spring in 2020, including from January to may, and includes all sea ice containing areas above 60 ° N.3. All dataset are divided into daily data. The single day data folder contains several CSV files, and each file contains the sea ice drift vector in a certain area.Each CSV file contains a total of six columns: start_ lat、Start_ lon、End_ lat、End_ Lon, azimuth angle, drift distance and INFO.Each row of data represents a sea ice drift vector, in which the first four columns record the starting point longitude and latitude, ending point longitude and latitude of the near real-time vectors, and the fifth column records the drift direction(degree) and drift distance (meters). The INFO column records the image number, imaging time, interval time and detailed spatial range of the CSV file. Wkt format fields.4. The daily data is contained in a folder, with about 300 CSV files per day, and the amount of data per day is 500mb-700mb5. Data storage adopts standard CSV file storage, which can be opened with Excel or any other software supporting CSV format.
