NOAA/WDS Paleoclimatology - Heywood - Drury Point - QUST - ITRDB MO084

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库（International Tree Ring Data Bank）与世界古气候学数据中心（World Data Center for Paleoclimatology）的档案资源。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，另有部分早材（earlywood）、晚材（latewood）宽度或木材密度的采集数据），同时附带年表（chronologies）——即基于多份树木年轮样本合成的对应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结果。各类数据均单独存储于独立的数据文件中，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
