Alces Bluff Tree Ring Data [Lloyd, A.]

Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Data 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). Each data type is stored in a separate data file; the data type is coded into the file name.

本数据集的树木年轮（tree ring）数据源自国际树木年轮数据库（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。数据包含原始树木年轮测量数据（多数为年度年轮宽度，另有部分采集样本的测量指标为早材宽度、晚材宽度或木材密度），以及年轮年表（chronologies）：由多个树木年轮样本整合得到的某一地点的标准化生长指数。每种数据类型均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。
