Below-ground hydraulic constraints during drought-induced decline in Scots pine

Dataset from the paper 'Below-ground hydraulic constraints during drought-induced decline in Scots pine'. Files: DOY refers to day of year 2012, idtree is tree identity and Class is defoliation class. Tree characteristics can be found in the supplementary materials of the paper. Variables are expressed in the same units as in the paper. WaterPotentials.csv - water potential data (predawn, PD, midday MD, difference) SapFlowDeltaPResistbc.csv - daily sap flow per unit leaf area (Jl_daily), delta pressure (deltaP), VPD,SWC, belowcrown resistance (r_bc). Resistbc_percent.csv - below-crown resistance as a percentage of total tree resistance
