Antarctic and Actic sea ice data set (1979-2019)


The original data of the Arctic and Antarctic sea ice data set is generated by the National Snow and Ice Data Center (NSIDC) through remote sensing data. The data format is GeoTIFF format and image format. The spatial resolution of the data is 25km and the time resolution is day. The data content is the sea ice range and sea ice density of the north and south poles. In this study, NetCDF format products are generated by post-processing the extent and density of sea ice in the north and south poles. The product data includes the sea ice range and sea ice density data of the north and south poles from 1979 to 2019. The time resolution is day by day, the coverage range is the South Pole and the north pole, and the horizontal spatial resolution is 12.5km. The data value of 1 in the sea ice range matrix indicates that the grid is sea ice, and the sea ice density is expressed by 0-1000. The grid value divided by 10 is the sea ice density value of the grid.


Data file naming and use method

File name: the sea ice data is stored in the format of NetCDF. The file name is "n_ yyyy MM DD. NC", where n represents the Arctic, s represents the Antarctic, yyyy represents the year, mm represents the month, and DD represents the day. For example, n_.nc represents this NetCDF file to describe the Arctic sea ice extent and concentration on January 2, 1979.
