The data records in detail the temperature observation data of snow layer, 5m ice layer, 10m ice layer, 30m ice layer, and 57m ice layer. Polar sea ice is an important component of the global climate system, and the climate effects of polar sea ice can range from local, regional to hemispheric and global in spatial scale, and from week, month, season to year or even several years or longer in time scale.
