  1. a) Winter (years 1992–2003) and b) summer (years 1992–2014). Statistics show the model averaged results from across the best supported models (listed in Additional file 1: Table S2). T depicts Temperature, R precipitation, DecJan the months of December and January combined, FebMar is February and March combined. SGS indicates the start of the growth season of trees.
