Description: Measurements of leaf carbon and nitrogen content collected from 68 tropical tree species. Data includes leaves collected from fully sunlit and shaded canopy strata as well as leaves for young, mature, old and senescent leaf ages. Data for each sample includes the relative age estimate, leaf canopy position and sample number. This data was collected as part of the 2017 NGEE-Tropics / NASA G-LiHT airborne campaign. This data package includes processed data for leaf carbon and nitrogen content (*.csv). Metadata files include data description (_dd.csv) for tabular data, site information (*.csv), sampling protocol (*.pdf) and the NGEE-Tropics FRAMES e-field log and file submission metadata (*.xlsx). See related datasets for sample details including photographs, leaf-level reflectance and transmittance spectra, leaf mass per area (LMA) and water content.
QA/QC: Full QA-QC
Methods Description: The area of sampled leaf material was determined by taking circular punches of known area. Samples were dried in a ventilated oven (60–70°C) to constant mass. Leaf dry mass was determined using a top pan balance (AND ER-60A; A&D Engineering, San Jose, CA USA). Dried, ground samples were weighed into tin capsules on a Mettler Toledo AX26 DeltaRange mass balance (Mettler Toledo, Columbus, OH USA). Leaf carbon and nitrogen was determined using a Perkin Elmer 2400 Series II CHNS/O Elemental Analyzer, used according to manufacturer's instructions (Perkin Elmer, Waltham, MA USA). Refer to included protocol for further information.
