NOAA/WDS Paleoclimatology - Brubaker - Rainy Pass 2 - PSME - ITRDB WA023

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.

本数据集源自国际树木年轮数据银行（International Tree Ring Data Bank）与世界古气候学数据中心（World Data Center for Paleoclimatology）的档案馆藏。多数数据集包含原始树轮测量数据：其中绝大多数为年度年轮宽度测量值，另有部分数据集收录早材宽度、晚材宽度或木材密度相关测量项；同时附带树轮年表——即由多组树轮样本整合得到的单站点标准化生长指数。部分数据集还包含气候变量重建结果。各类数据分别存储于独立的数据文件中，数据类型信息通过文件名进行编码标识。详细信息请参阅：http://www.ncdc.noaa.gov/paleo/treeinfo.htmll
