Environmental Working Group Joint U.S.-Russian Arctic Sea Ice Atlas, Version 1

The Environmental Working Group Joint U.S.-Russian Arctic Sea Ice Atlas is part of the NOAA@NSIDC Environmental Working Group (EWG) Atlases data collection.
The EWG Joint U.S.-Russian Arctic Sea Ice Atlas was developed by U.S. and Russian partners in the late 1990s. It is based on observations collected over the period 1950 through 1994 from satellite data, ice stations, icebreakers, and airborne ice surveys. Additionally, U.S. submarines operating in the Arctic over the period from 1977 through 1993 collected data used for a previously classified ice climatology. The Atlas contains four main sections: an introduction to Arctic sea ice, a section that describes primary sea ice data sets and analysis methods, a section with a graphical atlas containing two-dimensional color-coded ice charts and graphical products, and an Arctic sea ice data section. Note: The Russian chart component of this product has been replaced and updated by Sea Ice Charts of the Russian Arctic in Gridded Format, 1933-2006 and the U.S chart component by National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format, 1972-2007 and U.S. National Ice Center Arctic and Antarctic Sea Ice Concentration and Climatologies in Gridded Format.

美国-俄罗斯北极海冰图集（Environmental Working Group Joint U.S.-Russian Arctic Sea Ice Atlas）隶属于美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）与国家冰雪数据中心（National Snow and Ice Data Center, NSIDC）环境工作组（Environmental Working Group, EWG）图集数据集系列。
该美俄联合北极海冰图集由美俄合作机构于20世纪90年代末联合研发，其数据源自1950年至1994年间通过卫星遥感、冰站观测、破冰船勘测及航空冰况普查获取的实测资料。此外，1977年至1993年间在北极海域部署的美国潜艇所采集的数据，曾用于一份此前处于保密状态的海冰气候学研究。
该图集共设四大核心板块：北极海冰概况介绍、核心海冰数据集与分析方法说明、搭载二维彩色编码海冰图及可视化产品的图形图集板块，以及北极海冰专属数据板块。
备注：本产品的俄罗斯海冰图组分已由《1933-2006年网格化格式俄罗斯北极海冰图集（Sea Ice Charts of the Russian Arctic in Gridded Format, 1933-2006）》替代更新，美国海冰图组分则由《1972-2007年网格化格式国家冰中心北极海冰图集及气候学资料（National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format, 1972-2007）》与《美国国家冰中心网格化格式北极与南极海冰浓度及气候学资料（U.S. National Ice Center Arctic and Antarctic Sea Ice Concentration and Climatologies in Gridded Format）》完成替代更新。
