NOAA/WDS Paleoclimatology - Panthi - Rara - PCSM - ITRDB NPL063

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（多数为年度年轮宽度，部分涵盖早材宽度、晚材宽度或木材密度的采集集合），同时附带年轮年表——即由多组树木年轮样本整合得到的单站点标准化生长指数。部分此类数据集还包含气候变量重建成果。每一类数据均存储于独立的数据文件中，且数据类型编码于文件名内。详细信息请参阅：http://www.ncdc.noaa.gov/paleo/treeinfo.htmll
