20-Year Synthesis of Soil Respiration Data at Harvard Forest 1991-2008

All data on soil carbon flux (“soil respiration”) collected using chamber-based methods at Harvard Forest from a range of observational and experimental plots were collated, their units were harmonized, and geographic (locations) and environmental characteristics (soil series, drainage class, soil temperature, soil moisture, vegetation type, etc.) were identified for each observation. This yielded a dataset with 106,192 observations of soil respiration taken between 1991 and 2008. These data provide a unique resource for exploring spatial and temporal patterns in soil respiration in a range of common New England forest types.本数据集整合了哈佛大学森林（Harvard Forest）内采用箱法（chamber-based methods）于多组观测与实验样地中采集的土壤碳通量（soil carbon flux，即土壤呼吸（soil respiration））相关数据；统一了所有数据的计量单位，并为每条观测记录匹配了地理（位置）与环境特征信息，涵盖土系（soil series）、排水等级（drainage class）、土壤温度、土壤湿度、植被类型等。最终构建得到1991年至2008年间共计106192条土壤呼吸观测记录的数据集。该数据集可为探究新英格兰地区多种常见森林类型中土壤呼吸的空间与时间格局提供独特的研究资源。
