Leaf mass per area and leaf water content measurements from field survey in association with NEON AOP survey, East River, CO 2018

Leaf area, wet, and dry weights for leaf samples from sites where field sampling was conducted during the 2018 National Ecological Observatory Network (NEON) Airborne Observation Platform (AOP) imaging spectroscopy and lidar surveys in Gunnison County, Colorado. The sampling sites were located across East River, Washington Gulch, Slate River, and Coal Creek watersheds and contained a mixture of meadow, shrub, and tree sampling sites. This data package contains the leaf area and wet and dry weights for leaves from tree and shrub sampling sites, as well as samples for meadow species present within a given sampling area. Associated data packages contain species composition information at the plot level (DOI: 10.15485/1618130), as well as additional biogeochemical, microbial, and geophysical data as they become available. For full documentation, please see associated reference. This package contains zipped folders of all scans that were used for area calculations for both sampling sites (tree/shrub, site_scans.zip) as well as representative samples from a daily sampling area of meadow species that were found in the 1 m plots (meadow_area_scans.zip). It also contains the macro code that was used in ImageJ for processing of the area calculations. Finally, it includes excel files with the area (cm2), wet weight (g), dry weight (g), leaf mass per area (LMA, g/m2), and leaf water content (%) for each set of scans.

本数据集收录2018年美国国家生态观测站网络（National Ecological Observatory Network, NEON）航空观测平台（Airborne Observation Platform, AOP）于科罗拉多州甘尼森县开展成像光谱与激光雷达勘测期间，野外采样获取的叶片样本的叶面积、鲜重与干重数据。采样点位覆盖东河（East River）、华盛顿溪谷（Washington Gulch）、板岩河（Slate River）与煤溪（Coal Creek）流域，涵盖草甸、灌丛与林地三类采样样地。本数据包包含林地与灌丛样地的叶片叶面积、鲜重与干重数据，以及对应采样区域内草甸物种的叶片样本数据。关联数据包包含样地尺度的物种组成信息（DOI: 10.15485/1618130），以及后续可获取的其他生物地球化学、微生物与地球物理相关数据。完整文档请参阅关联参考文献。本数据包包含两类用于叶面积计算的扫描文件压缩包：适用于全部采样样地（林地/灌丛）的site_scans.zip，以及1米样地内草甸物种每日采样区域的代表性样本扫描包meadow_area_scans.zip；同时包含用于ImageJ软件开展叶面积计算的宏代码。此外，本数据包还提供Excel表格文件，记录每组扫描样本的叶面积（单位：cm²）、鲜重（单位：g）、干重（单位：g）、叶质量面积比（Leaf Mass per Area, LMA，单位：g/m²）与叶片含水量（单位：%）。
