Purpose: Peatlands store disproportionally large amounts of carbon per unit area, a function that is dependent on maintaining high and stable water tables. Climate change is likely to negatively impact carbon storage in peatlands, in part due to increases in vapour pressure deficit (VPD) driving higher evaporation (E) rates. However, the response of E to increasing VPD depends on the dominant vegetation type within peatlands. In this study, we used multiple years of eddy covariance (EC) measurements to compare E regimes at two peatlands with contrasting vegetation types – Kopuatai bog in Aotearoa / New Zealand, dominated by the vascular wire rush Empodisma robustum, and Mer Bleue bog in Canada, a “typical” shrub- and moss-dominated Northern Hemisphere peatland. We examined seasonal variability in E and equilibrium E (Eeq), energy balance partitioning, and the response of E, evaporative fraction (EF), and canopy conductance (gc) to VPD.
Abstract: Version 2 of datasets used for analyses in the paper titled "Peatland evaporation across hemispheres: contrasting controls and sensitivity to climate warming driven by plant functional types" submitted to Biogeosciences. There are two datasets - one from Kopuatai bog, Aotearoa New Zealand, and one from Mer Bleue bog, Canada - which contain gap-filled and filtered data that were used to produce the results of our study.
Supplemental Information Summary: Due to improvements made to our methodology following the paper peer review process, the data in this version slightly differs from that of the previous version. Information on these revisions can be found in the README file below or the Discussion/Peer Review tab of our paper.
