Processed Soil Respiration at the TRACE experimental Warming project, Aug 2015 - Sep 2017, Sabana, Luquillo, Puerto Rico

This data package contains processed measurements of soil carbon dioxide (CO₂) efflux collected using LI-COR LI-8100 soil respiration chambers at the Tropical Responses to Altered Climate Experiment (TRACE) located at the Sabana Field Research Station near Luquillo, Puerto Rico. The TRACE site is a mature, closed-canopy tropical wet forest within the Luquillo Experimental Forest. These data quantify soil surface CO₂ fluxes from both ambient (control) and experimentally warmed plots to evaluate how long-term soil warming affects belowground carbon cycling in tropical ecosystems. The data files include time-series tables of CO₂ flux (µmol CO₂ m⁻² s⁻¹), soil temperature (°C), and ancillary environmental variables, stored in comma-separated values (CSV) format and viewable with any text editor, spreadsheet, or statistical software (e.g., R, Python, Excel). Associated metadata describe plot identifiers, measurement intervals, and processing steps. These data were generated to address the research question: How does sustained soil warming influence soil respiration and carbon flux dynamics in tropical wet forests?

本数据集包含经预处理的土壤二氧化碳（CO₂）排放通量测量数据，采集自波多黎各卢奎略附近萨瓦纳野外研究站的热带气候改变响应实验（Tropical Responses to Altered Climate Experiment, TRACE）场地，数据获取采用LI-COR LI-8100土壤呼吸室。该TRACE试验场地隶属于卢奎略实验森林，为一处成熟的密闭冠层热带湿润林。本数据集量化了对照（环境背景）样地与实验增温样地的土壤表面CO₂通量，用于评估长期土壤增温对热带生态系统地下碳循环的影响。数据文件包含CO₂通量（单位：µmol CO₂ m⁻² s⁻¹）、土壤温度（单位：°C）及辅助环境变量的时间序列表格，以逗号分隔值（CSV）格式存储，可通过任意文本编辑器、电子表格或统计软件（如R、Python、Excel）读取查看。配套元数据包含样地标识符、测量间隔与数据处理流程说明。本数据集旨在解答如下科学问题：持续土壤增温如何影响热带湿润林的土壤呼吸与碳通量动态？
