Leaf gas exchange (BNL-PNNL collaboration), San Lorenzo, Panama, 2020

This data package contains Photosynthetic CO2 response (ACi curves) and Light Response (AQ) of mature sunlit canopy leaves of 11 species from PA-SLZ, February 2020. Branches were cut from the top of the canopy and re-cut under water. Fitted Vcmax and Jmax photosynthetic parameters were derived from measured data as well as the convexity, light use efficiency and apparent quantum yield. This data was collected as a collaboration between Brookhaven National Laboratory (BNL) and Pacific Northwest National Laboratory (PNNL), and is a subset of the 2020 BNL Panama campaign. The species included in this dataset are: Apeiba membranacea, Carapa guianensis, Cespedesia spathulate, Jacaranda copaia, Lonchocarpus heptaphyllus, Pera arboea, Pourouma bicolore, Symphonia globulifera, Tachigali versicolor, Tapirira guianensis, and Virola sebifera. The files included in this data package are in .csv and .pdf format, with two Excel files containing additional metadata. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival Acknowledgement: This research was supported as part of NGEE-Tropics, funded by the U.S. Department of Energy, Office of Science, Office of Biological and Environmental Research under contract no.

本数据包包含2020年2月采自PA-SLZ区域的11种成熟阳生冠层叶片的光合CO₂响应曲线（ACi curves）与光响应曲线（AQ curves）。实验样品枝条采自冠层顶部，并在水下进行二次剪截以防止气泡侵入输导组织。基于实测数据拟合得到的光合参数包括最大羧化速率（Vcmax）、最大电子传递速率（Jmax）、曲度、光能利用效率及表观量子产额。本数据集由布鲁克海文国家实验室（BNL）与太平洋西北国家实验室（PNNL）合作采集，是2020年BNL巴拿马野外考察项目的子集数据。本数据集涵盖的物种包括：Apeiba membranacea、Carapa guianensis、Cespedesia spathulate、Jacaranda copaia、Lonchocarpus heptaphyllus、Pera arboea、Pourouma bicolore、Symphonia globulifera、Tachigali versicolor、Tapirira guianensis以及Virola sebifera。本数据包包含的文件格式为.csv与.pdf，另有两份附带补充元数据的Excel文件。本数据集最初发布于NGEE Tropics Archive，现于ESS-DIVE平台进行镜像存档以实现长期留存。致谢：本研究作为NGEE-Tropics项目的一部分得到资助，该项目由美国能源部科学办公室生物与环境研究局根据合同编号DE-SC0012704提供支持。
