Figure S2 Mean day of year (DOY) of SI-x leaf (left) and LAI25% (right) averaged across the Northern Hemisphere (25°N-85°N) for each model member and the observational datasets. Mean SI-x leaf and LAI25% are calculated over 1950-2014 (blue), 1981-2014 (magenta), and 2015-2099 (orange) periods and weighted by area weight. Ensemble means averaged across the first member of each model (26 models for SI-x leaf and 7 models for LAI25%) are plotted vertically for comparison.
