Fig. 2: European beech radial growth and forest productivity during summer JSL extremes.

Anomalies in European beech radial growth (a, c, e, g) and DGVM-estimated forest GPP (b, d, f, h) for the years showing the largest summer JSL anomalies (i.e., D90 and D10 of jslPC1 and jslPC2 scores, see Supplementary Table 1). Anomalies are expressed as percentages from the mean for the period 1950–2005. Black circles indicate significant anomalies (p < 0.05).
