资源简介：
Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name. For details please see: http://www.ncdc.noaa.gov/paleo/treeinfo.htmll
本数据集源自国际树木年轮数据库（International Tree Ring Data Bank）与古气候学世界数据中心（World Data Center for Paleoclimatology）的档案馆藏。多数数据集包含原始树木年轮测量数据：绝大多数为年轮宽度数据，另有部分数据集采集了早材宽度、晚材宽度或木材密度数据；同时还附带年轮年表数据——即基于多组树木年轮样本合成的样地标准化生长指数。部分数据集还包含气候变量重建结果。各类数据均存储于独立的数据文件中，数据类型编码内嵌于文件名内。如需获取详细信息，请参阅：http://www.ncdc.noaa.gov/paleo/treeinfo.htmll
