ATLANTIC_CH04_Product_5 / Total ice cover (1915-2014)

Pentadal time-series of the area in the North Atlantic (IHO, 1953) where ice occurred. On a 1 degree grid find all cells that experienced ice in at least 1 month of each 5 year period between 1915 and 2014, and then calculate the total area that these cells covered.本数据集为依据国际海道测量组织（International Hydrographic Organization, IHO）1953年标准划定的北大西洋海域内海冰出现区域的五年期时间序列。基于1°经纬度网格，筛选出1915年至2014年间每个五年周期内至少有1个月出现过海冰的网格单元，进而计算符合条件网格单元的总面积。
