MESI: a database of terrestrial global change experiments
收藏资源简介:
effects of experimental eCO2, warming, nutrient addition and/or water addition/removal on carbon and nutrient cycle related variables New in v1.0.3: Improved accuracy and further completion of the following variables: • longitude (lon) of the experiment site (site) • latitude (lat) of the experiment site (site) • elevation (elevation) of the experiment site (site) • ecosystem type (ecosystem_type) • experiment type: field/FACE, open-top chamber, pot (experiment_type and fumigation_type) • treatment level (particularly c_c, c_t, n_c, n_t, p_c, p_t, k_c, k_t) • sampling year of the experiment (sampling_year and duration) • warming type (w_t1) • some site (site), study (study) and experiment (exp) names Response variable (response) 'leaf_area' replaced by leaf_area_leaf, leaf_area_plant, leaf_area_eco Response variable (response) 'leaf_biomass' replaced by leaf_biomass_leaf, leaf_biomass_plant, leaf_biomass_eco
本数据集聚焦于实验性升高CO₂浓度(eCO₂)、增温、养分添加及/或水分添加/移除对碳循环与养分循环相关变量的影响。 版本1.0.3更新内容: 优化以下变量的精度并完成进一步补全: • 实验站点(site)的经度(longitude,简写lon) • 实验站点(site)的纬度(latitude,简写lat) • 实验站点(site)的海拔高度(elevation) • 生态系统类型(ecosystem_type) • 实验类型:野外实验、自由大气CO₂富集(FACE)、开顶箱、盆栽(对应字段:experiment_type与fumigation_type) • 处理水平(具体涵盖c_c、c_t、n_c、n_t、p_c、p_t、k_c、k_t) • 实验采样年份(sampling_year)与实验周期(duration) • 增温类型(w_t1) • 部分站点(site)、研究(study)及实验(exp)的名称 原响应变量(response)“leaf_area” 已替换为leaf_area_leaf、leaf_area_plant、leaf_area_eco 原响应变量(response)“leaf_biomass” 已替换为leaf_biomass_leaf、leaf_biomass_plant、leaf_biomass_eco
