南北极海冰数据集（1979-2019）

南北极海冰数据集原始数据由美国国家冰雪数据中心(The National Snow and Ice Data Center：NSIDC)通过遥感数据生成，数据格式为geotiff格式与image格式，数据空间分辨率为25km，时间分辨率为日。数据内容是南北极的海冰范围及海冰密集度。本研究工作通过对南北极海冰的范围与海冰密集度后处理后生成netcdf格式产品。产品数据包含1979-2019年南北极海冰范围与海冰密集度数据，其时间分辨率为逐日，覆盖范围为南极与北极，水平空间分辨率为12.5km，海冰范围矩阵中数据值为1表示该网格为海冰，海冰密集度用0-1000表示，该网格值除以10即为该网格海冰密集度值。

The raw data of the Arctic and Antarctic sea ice dataset was generated by the National Snow and Ice Data Center (NSIDC) using remote sensing data. The data is available in GeoTIFF and image formats, with a spatial resolution of 25 km and a daily temporal resolution, and covers sea ice extent and sea ice concentration over the polar regions. This study generated NetCDF-format products by post-processing the Arctic and Antarctic sea ice extent and concentration data. The product dataset includes sea ice extent and concentration data for the Arctic and Antarctic from 1979 to 2019, with a daily temporal resolution, covering both polar regions, and a horizontal spatial resolution of 12.5 km. In the sea ice extent matrix, a value of 1 indicates that the grid cell contains sea ice. Sea ice concentration is represented by values ranging from 0 to 1000, where dividing the grid cell value by 10 yields the actual sea ice concentration value.
