北极海冰季节统计数据集(1979-2012)

Arctic Seasonal Sea Ice Statistics Dataset(1979-2012)

北极海冰范围的变化是全球气候变化的一个指示剂。作者在美国冰雪中心发布的北极海冰监测卫星遥感密集度数据基础上,按照海冰密集度大于15%的网格点计算,获得1979-2012年北极海冰季节统计数据集。数据集包括:(1)全北极1979-2012年海冰范围统计数据(Arctic Seasonal Sea Ice19792012-1),包括四季海冰范围统计数据表,全北极海冰范围异常场数据统计表;春季和夏季北极区域海冰范围滑动t统计表;(2)北极各分区海冰范围统计数据,其中包括1979-2012年各季节东半球、西半球、太平洋扇区和大西洋扇区四个海区海冰分布原始场和异常场共8个数据表(Arctic Seasonal Sea Ice19792012-2);(3)2007年9月与2012年9月北极冰密集度数据(Arctic Seasonal Sea Ice19792012-3);(4)北极区域1979-1988、1989-1998、1999-2008和2009-2012的春季、夏季、秋季、冬季的季节平均冰密集度异常数据及对应的空间分布数据(Arctic Seasonal Sea Ice19792012-4);(5)春、夏、秋、冬北极海冰小波分析数据(Arctic Seasonal Sea Ice19792012-5)。本数据集的分析研究成果发表在《极地研究》2015年27卷第2期。

The change of Arctic sea ice is an indicator reflecting climate change.Based on sea ice concentration data published by the National Snow and Ice Data Center of USA(NSIDC),the arctic seasonal sea ice statistics dataset(less than 15%areas of sea ices was not included)was developed.The dataset includes:(1)Arctic seasonal sea ice statistics data in 1979-2012,including three tables in the data file:Table 1 Arctic seasonal sea ice statistic data;Table 2 Arctic seasonal sea ice anomaly statistic data;Table 3 Arctic sea ice extent and statistics of MTT(Moving t-test technique)in spring and summer.(2)Arctic regional and seasonal sea ice statistics data in 1979-2012,including statistic data of the sea ice in the eastern hemisphere,the western hemisphere,the Pacific sector and the Atlantic sector(eight tables).(3)The spatial data of sea ice concentration in Arctic in September 2007 and 2012.(4)The spatial data of Arctic seasonal sea ice concentration anomaly in 1979-1988,1989-1998,1999-2008 and 2009-2012.(5)Wavelet analysis data of seasonal Arctic sea ice extent.The dataset was archived in.xlsx,.shp and.dat formats with the data size of 52.9 MB.
