NOAA/WDS Paleoclimatology - Tropical Belt 800 Year Early Spring Northern Boundary Reconstruction

This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Climate Reconstruction. The data include parameters of climate reconstructions|tree ring with a geographic location of Northern Hemisphere. The time period coverage is from 747 to -53 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.

本归档古气候学（Paleoclimatology）研究数据集可从美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）下属的国家环境信息中心（National Centers for Environmental Information, NCEI）获取，该中心隶属于古气候学世界数据服务中心（World Data Service for Paleoclimatology, WDS）。该研究对应的NCEI研究类型为气候重建（Climate Reconstruction）。数据集涵盖气候重建相关参数及树木年轮（tree ring）数据，地理覆盖范围为北半球。数据集的时间覆盖区间为距今747年至距今-53年（BP，即以距1950年为基准的日历年份）。如需了解参数及研究地点的详细信息，请查阅元数据（metadata）文档。使用本数据集时，请引用本研究。
