Pantropical Tree Sapwood Hydraulic Properties, 1991 - 2014

Author(s): Christoffersen B


Dataset Information

Site ID: XX-PTr

Site Name: Pantropical site

Variables: Sapwood pressure-volume (PV) Parameters

Date Range: April 1, 1991 - Sept. 29, 2014

Description: This data package contains sapwood pressure-volume parameters including osmotic potential at full turgot, turgor loss point, bulk elastic modulus, and others, determined by curve fitting to raw isotherm data (paired measurements of water content and water potential). Raw data were digitized from published figures. Data are from natural tropical and subtropical forests or savannas and span rainfall gradients from deciduous dry tropical forests to everwet tropical forests, and come from the following countries: Argentina, Panama, Brazil, Costa Rica, and Madagascar. Included in the attached zip file are four CSV files. sapwood_PV_recal_headers.csv: description of variables in the two files below sapwood_PV_recal_corrected.csv: bias-corrected sapwood PV data (see Methods in the associated reference) sapwood_PV_recal_uncorrected.csv: uncorrected sapwood PV data (see Methods in the associated reference) sapwood_PV_references.csv: citation, bibliographic reference, and DOI for the published references from which data were extracted.

QA/QC: None

Methods Description: Please see the referenced publications for data collection methods.

Access Level: Public

Originating Institution(s): Los Alamos National Laboratory

Sponsor Organization(s): European Union Seventh Framework Programme under the project AMAZALERT (Grant Agreement No. 282664 to Patrick Meir)
