Fig. 3

Tree ring formation in Cedrus libani with site specific microclimatic data. Shown are tree ring width resulting from radial growth with error bars indicating standard deviation among trees, daily maximum (dark gray line), mean (black line) and minimum (gray line) air temperature and daily mean stem temperature of sampled trees (red line) during the growing season of 2013. Vertical gray bands highlight the specific weather conditions over 14 days pre-running the first observation of enlarging cells and thus the beginning of radial increment. Precipitation data (monthly sum) are shown for O1 (grey, dotted bars), for T3 and T1. White bars show precipitation data from the Elmali Meteorological Station, hatched bars indicate precipitation data measured at the respective site, double-hatched bars show modelled precipitation data where site-specific precipitation data were missing (indicated with a star)
