ICESat L4 Seasonal Gridded Sea Ice Thickness, Version 1

This data set reports seasonal gridded winter sea ice thickness across the Arctic Ocean. Sea ice thickness is estimated using ICESat/GLAS L3A Sea Ice Freeboard data and NASA Eulerian Snow On Sea Ice Model (NESOSIM) Version 1.1 snow loading. This data set is a historical complement to ICESat-2 L4 Monthly Gridded Sea Ice Thickness.本数据集发布了北冰洋冬季季节性网格化海冰厚度数据。海冰厚度通过ICESat/GLAS L3A海冰干舷数据，以及美国国家航空航天局（NASA）欧拉型海冰积雪模型（NESOSIM，全称NASA Eulerian Snow On Sea Ice Model）1.1版本的积雪载荷估算得到。本数据集可作为ICESat-2 L4网格化月度海冰厚度数据的历史补充数据集。
