Description:
This data package contains leaf water potential data from the Barro Colorado Island (BCI), Parque Natural Metropolitano (PNM), and Bosque Protector San Lorenzo (SLZ) NGEE Tropics field sites in Panama. Pre-dawn and diurnal leaf water potential were measured on a monthly basis from February to May 2016 at SLZ and PNM. Data from BCI are only available for the month of March. This data was collected as part of the 2016 El Niño-Southern Oscillation (ENSO) campaign. Included in the attached zip file are data and metadata folders. The single data file "2016ENSO_Panama_LWP" has been provided in both Excel and CSV formats for usability purposes. The metadata file "Metadata_description_2016_ENSO_Panama" provides protocols, site descriptions, equipment information, and more, and has been provided in .docx and PDF file formats. See related datasets (existing and future) for further sample details, leaf spectra, leaf mass area (LMA), gas exchange and leaf chemistry data.
VERSION 2 update. The identification of a species from the PNM site has been corrected as follows: the identification of the tree initially identified as Pseudosamanea guachapele (ALBIED) has been revised to Albizia adinocephala (ALBIAD). The updated data package includes revised data, metadata and protocol documents updated to reflect this change.
QA/QC:
Full QA-QC
Methods Description:
Diurnal gas exchange, CO2 response (ACi curves), leaf water potential and leaf spectra were recorded from top of canopy at monthly intervals (Feb, Mar, Apr, May) during the 2016 ENSO period. Each monthly measurement round comprised four measurement days; one day of diurnal measurements, with some ACi, and one day focused on ACi, at each of two sites. Leaf water potential and samples for NSC and Ph were only collected from diurnal gas exchange samples. In March, measurements were also made at BCI (leaf water potential and leaf sampling only. No gas exchange or spectra). QA/QC was undertaken to check: sample IDs have correct format and are unique; species codes are valid; leaf water potential (LWP) data in the correct units and within reasonable range; samples are cross referenced against those in related data sets.
