Abstract
Abstract. Plant transpiration links physiological responses of
vegetation to water supply and demand with hydrological, energy, and carbon
budgets at the land–atmosphere interface. However, despite being the main
land evaporative flux at the global scale, transpiration and its response to
environmental drivers are currently not well constrained by observations.
Here we introduce the first global compilation of whole-plant transpiration
data from sap flow measurements (SAPFLUXNET, https://sapfluxnet.creaf.cat/, last access: 8 June 2021).
We harmonized and quality-controlled individual datasets supplied by
contributors worldwide in a semi-automatic data workflow implemented in the
R programming language. Datasets include sub-daily time series of sap flow
and hydrometeorological drivers for one or more growing seasons, as well as
metadata on the stand characteristics, plant attributes, and technical
details of the measurements. SAPFLUXNET contains 202 globally distributed
datasets with sap flow time series for 2714 plants, mostly trees, of 174
species. SAPFLUXNET has a broad bioclimatic coverage, with
woodland/shrubland and temperate forest biomes especially well represented
(80 % of the datasets). The measurements cover a wide variety of stand
structural characteristics and plant sizes. The datasets encompass the
period between 1995 and 2018, with 50 % of the datasets being at least 3 years long. Accompanying radiation and vapour pressure deficit data are
available for most of the datasets, while on-site soil water content is
available for 56 % of the datasets. Many datasets contain data for species
that make up 90 % or more of the total stand basal area, allowing the
estimation of stand transpiration in diverse ecological settings. SAPFLUXNET
adds to existing plant trait datasets, ecosystem flux networks, and remote
sensing products to help increase our understanding of plant water use,
plant responses to drought, and ecohydrological processes. SAPFLUXNET version
0.1.5 is freely available from the Zenodo repository (https://doi.org/10.5281/zenodo.3971689; Poyatos et al., 2020a). The
“sapfluxnetr” R package – designed to access, visualize, and process
SAPFLUXNET data – is available from CRAN.
