三极过去2000年古气候数据集
收藏资源简介：
表格1 自述文件 表格2 用于区域温度重建的代理数据系列的元数据（数据库S2）非洲记录列在元数据库中，但没有单独列出，因为没有提供区域温度重建； 表格3南极个人记录 詹姆斯罗斯岛（JRI）记录，仅用于西南极重建，非主要的南极重建或替代重建； 表格4北极个人记录 多年样本由年时间中点的单值表示，多年样本后面的列表列出了每个样本所代表的年数； 表格5亚洲个人记录； 表格6澳大拉西亚个人记录； 表格7欧洲个人记录 树环数据通常是在经度几度范围的区域内聚合，但Tor92记录除外。该区域树木记录仅在Torneträsk湖和Car09记录附近采样； 表格8北美基于花粉重建的记录 每个区域的位置由其质心表示，年份代表30年间间隔的中点 表格9由PAGES 2k ID代表的北美基于树木的重建的录 第一组94条记录是1500-1980部分重建中使用的数据 第二组93个记录是用于驱动重建的1200-1499部分的数据，以及它们对应的值1500-1987 突出显示如下： 1）黄色突出显示Luckman和Sauchin年代表根据元数据选项卡移动到他们的位置 2）大粗体边框表示为1200-1987校准数据集添加1500-1987的数据值 3）第5行和第6行中的粗体边框元数据和ITRDB标识符表示PAGES 2k ID号不在“元数据”选项卡中显示的序列中的记录-请注意这些标识符（及其ITRDB记录名称）应用于正确的数据集 表格10南美洲的记录
Table 1: Readme File Table 2 Metadata of proxy data series for regional temperature reconstruction (Database S2). African records are listed in the meta-database but not individually presented, as no regional temperature reconstruction was provided; Table 3 Individual Antarctic Records. James Ross Island (JRI) records are only used for West Antarctic reconstruction, not for primary Antarctic reconstruction or alternative reconstructions; Table 4 Individual Arctic Records. Multi-year samples are represented by a single value at the midpoint of the annual time period; the list following the multi-year sample specifies the number of years each sample represents; Table 5 Individual Asian Records; Table 6 Individual Australasian Records; Table 7 Individual European Records. Tree ring data are typically aggregated over regions spanning several degrees of longitude, with the exception of the Tor92 record. Tree records for this region were only sampled near Lake Tornetrask and the Car09 record; Table 8 Pollen-based reconstruction records for North America. The location of each region is represented by its centroid, and the year represents the midpoint of the 30-year interval; Table 9 Tree-based reconstruction records for North America represented by PAGES 2k IDs. The first set of 94 records is the data used in the 1500–1980 partial reconstruction. The second set of 93 records is the data used to drive the 1200–1499 partial reconstruction, along with their corresponding values for 1500–1987. Highlights are as follows: 1) Yellow highlights: Luckman and Sauchin chronologies were relocated to their correct positions per the metadata tab; 2) Large bold borders: Data values for 1500–1987 were added to the 1200–1987 calibration dataset; 3) Bold borders in rows 5 and 6: Metadata and ITRDB identifiers for records where the PAGES 2k ID number does not appear in the sequence listed on the "Metadata" tab — please note that these identifiers (and their ITRDB record names) should be applied to the correct dataset; Table 10 Records from South America;
