Leaf structural and chemical traits, and BNL field campaign sample details, San Lorenzo, Panama, 2020

This data package includes leaf traits, canopy traits and sample details for leaves from 71 species sampled from the San Lorenzo forest canopy crane site, Panama (PA-SLZ) during the BNL field campaign in January to March 2020. Each leaf sample is described with species, phenological stage and location within vertical canopy profiles. Leaf area index (LAI) and height is presented for each canopy profile location. Leaf mass per area (LMA), leaf water content (LWC) and leaf carbon and nitrogen content are included for a subset of the samples. This data package includes sample details, processed data for leaf traits and LAI (*.csv), LAI raw data (compressed as *.zip) and digital camera images (*.jpg, compressed as *.zip) of the leaf samples. Metadata files include data descriptions (_dd.csv) for tabular data, a list of all species sampled during the campaign (*.csv) and a detailed description of the field campaign protocol and methods (*.pdf). See related datasets for leaf gas exchange, leaf water potential and leaf spectral measurements made on the samples described here.

本数据包包含2020年1—3月BNL野外考察期间，于巴拿马圣洛伦佐森林冠层塔吊样地（PA-SLZ）采集的71个物种的叶片性状、冠层性状及样品详细信息。每份叶片样品均记录了物种信息、物候期及冠层垂直剖面内的采样位置；每份冠层剖面位置均提供了叶面积指数（Leaf Area Index，LAI）与冠层高度数据。部分样品测定了比叶质量（Leaf Mass per Area，LMA）、叶片含水量（Leaf Water Content，LWC）以及叶片碳、氮含量。本数据包涵盖样品详情、叶片性状与叶面积指数的处理后数据（*.csv格式）、叶面积指数原始数据（压缩为*.zip格式）以及叶片样品的数码相机影像（*.jpg格式，压缩为*.zip格式）。元数据（Metadata）文件包括表格数据的数据说明文档（_dd.csv）、本次野外考察采集的所有物种名录（*.csv格式）以及野外考察方案与方法的详细说明文档（*.pdf格式）。可参考相关数据集，获取本研究中针对上述样品开展的叶片气体交换、叶片水势及叶片光谱测量数据。本数据集最初发布于NGEE Tropics Archive，现由ESS-DIVE镜像归档以实现长期留存。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（U.S. Department of Energy）科学办公室生物与环境研究办公室根据合同编号DE-SC0012704提供支持。
