NOAA/WDS Paleoclimatology - Lamarche - Lockley Spur Road - PHAS - ITRDB AUSL014

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，涵盖树木年轮（Tree Ring）相关数据。多数数据集包含原始树木年轮测量值：其中绝大多数为年轮宽度（annual ring width），另有部分数据集集合收录早材（earlywood）、晚材（latewood）宽度或木材密度（wood density）数据；此外还包含年表（chronologies），即由多份树木年轮样本汇编得到的单站点标准化生长指数。部分此类数据集还附带气候变量重建结果。每种数据类型均单独存储于一个数据文件中，且数据类型编码内嵌于文件名内。详细信息请参阅：http://www.ncdc.noaa.gov/paleo/treeinfo.htmll
