Spatial and temporal variations in aboveground woody carbon storage for cerrado forests and woodlands of Mato Grosso, Brazil

Data for tree circumference (cm) at breast height (1.3 m), diameter (cm), height (m), aboveground woody biomass (AGWB; kg/tree), aboveground woody C (AGWC; kgC/tree), aboveground woody C pool size (MgC/ha) and aboveground woody C storage (MgC/ha*y) cerrado forests and woodlands of the Pantanal (PAN) and the Cuiaba Basin (CB) of Mato Grosso, Brazil. Data for you the years 2011-18. Data files are MS Excel files with formulas preserved to illustrate calculations.

Measured quantities include tree circumference at breast height, tree wood density, wood C concentration, and tree density. Tree height was estimated from diameter according to Schöngart et al. (2011), tree biomass was calculated according to Chave et al. (2015). See Vourlitis et al. (2013, 2014, and 2015) for a detailed description of site characteristics and measurement methods.

本数据集涵盖巴西马托格罗索州潘塔纳尔（Pantanal, PAN）与库亚巴盆地（Cuiaba Basin, CB）的塞拉多（Cerrado）森林及稀树草原的多项监测数据，包括树木胸高（breast height，1.3米处）周长（厘米）、直径（厘米）、树高（米）、地上木质生物量（aboveground woody biomass, AGWB; 千克/株）、地上木质碳（aboveground woody C, AGWC; 千克碳/株）、地上木质碳库容量（MgC/ha）及地上木质碳储量（MgC/ha·y）。数据覆盖2011至2018年，数据文件为保留计算公式以展示计算过程的MS Excel文件。

实测指标包括树木胸高周长、木材密度、木材碳浓度与树木密度。树高依据Schöngart等（2011）提出的方法由直径估算得到，树木生物量则根据Chave等（2015）的异速生长模型计算得出。关于样地特征与测量方法的详细描述，可参阅Vourlitis等（2013、2014、2015）的相关研究。
