    Description of key files - climate_arranged_day0.Rds – aligned climate data according to the onset day - climate_raw.Rds – aggregated climate data into hourly estimates - d13cAtmCorr.Rds – atmospherically corrected shot-level δ13C for each site and tree - d13c_mean. Rds – atmospherically corrected shot-level δ13C for each site, averaged across individual trees. - climate_VPD_soil.Rds – processed VPD and SWP data - climate_smoothed_method_figure.Rds – climate data used for Figure 1 - df_max_day. Rds – calculated maximum day of year for all onset days - "1 arrange climate according to day0.R" – R script to arrange climate data according to the onset day - "2 dendroTools analysis and heatmaps.R" – R script to calculate heatmaps of daily correlations - "3 cross-correaltion analysis.R" – R script to perform the cross-correlation analysis to obtain the maximal correlation coefficient for a range of potential end days - "4 linear models.R" – R script to fit linear models between δ13C and VPD and SWP
