Author(s): Serbin S; Meng R; Wu J; Ely K


Dataset Information

Site ID: PR-CAM; PR-CAR; PR-FLM; PR-SB2; PR-UPR

Site Name: CAM2: Cambalache State Forest; CAR1: Carite State Forest; Fundacion Luis Munoz Marin (FLMM); SB2: Sabana 2; International Institute of Tropical Forestry

Variables: Leaf spectra

Date Range: March 3, 2017 - March 9, 2017

Description: Measurements of leaf full-spectrum (i.e. 350-2500 nm) reflectance and transmittance across 54 tropical tree species from five sites in Puerto Rico. Sites are located in the Cambalache State Forest, Carite State Forest, Sabana Field Station, Fundacion Luis Munoz Marin and at the International Institute of Tropical Forestry at the University of Puerto Rico. 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. See related datasets for sample details including photographs, leaf traits including leaf mass per area (LMA), water content, and leaf carbon and nitrogen.

QA/QC: Full QA-QC

Methods Description: Reflectance spectra were measured on detached leaves from five sites in Puerto Rico. Leaf reflectance spectra were measured with a SVC HR-1024i Spectroradiometer, w/ SVC leaf clip attachment or Spectral Evolution PSRplus spectroreadiometer. Relative reflectance is reported, where the reflectance calculated as the ratio of the radiance or DN (digital number) of the target (i.e. leaf) divided by the radiance or DN of the Spectralon standard for each instrument channel.
