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
本数据集涵盖取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）档案库的树木年轮数据。多数数据集包含原始树木年轮测量数据（以逐年年轮宽度为主，部分数据集收录早材宽度、晚材宽度或木材密度），同时配套树木年轮年表——即由多份树木年轮样本整合得到的对应站点的标准化生长指数。部分数据集还附带气候变量重建结果。每一类数据均存储于独立的数据文件中，数据类型以编码形式嵌入文件名。详细信息请参阅：http://www.ncdc.noaa.gov/paleo/treeinfo.htmll
