Extended Data Fig. 3: Changes in the leaf unfolding dates of six tree species in Europe from period 1951–1979 to 1980–1999 and to 2000–2019, and the potential contributions of changes in winter chilling and spring forcing to these changes.
From: Deciphering the multiple effects of climate warming on the temporal shift of leaf unfolding
ΔDdf0 is the changes in date when dormancy is released (1st column). ΔDTA0 is the potential changes in the duration (in day) of forcing accumulation stage caused by rising forcing requirement due to chilling deficiency (2nd column). ΔDFD is the potential changes in the duration (in day) of forcing stage caused by changes in spring forcing temperatures (3rd column). Grid cells with insignificant (p>0.05 based on one-sample t-test) change are showed in grey. Here we only show the average change of each metrics for all samples within each 0.25°×0.25° grid cell.
