NOAA/WDS Paleoclimatology - Meko - Boles Creek - JUOC - ITRDB CA629

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.

本数据集取材于国际树木年轮数据库（International Tree Ring Data Bank）及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：绝大多数为逐年年轮宽度，另有部分早材宽度、晚材宽度或木材密度的测量集合；同时附带年表（chronologies）——即基于多个树木年轮样本整合得到的单站点标准化生长指数。部分数据集还配套提供气候变量重建结果。各类数据均单独存储于独立的数据文件中，文件名中嵌入了对应数据类型的编码标识。详细信息请参阅：http://www.ncdc.noaa.gov/paleo/treeinfo.htmll
