September - October Ensemble Mean and Standard Deviation Antarctic Sea Ice Concentration Reconstruction, 1905-2020

Ensemble mean and standard deviation across the 100+ ensemble members for Seasonal Antarctic sea ice concentration reconstructions, 1905-2020, for September-October season (SON). Data are gridded on the 25x25km polar stereographic projection, like sea ice data from NSIDC.本数据集为1905年至2020年9-10月季节（标注为SON）的南极海冰密集度重建序列的集合平均与标准差，该统计量基于100余个集合成员计算得到。数据采用25×25公里极立体投影进行网格化处理，其投影标准与美国国家冰雪数据中心（NSIDC）的海冰数据一致。
