Extended Data Fig. 7: Spatial pattern in the Pearson’s correlation coefficient between seasonal mean NDVI and the SPEI at the 3-month timescale (SPEI3) in different seasons.
From: Widespread spring phenology effects on drought recovery of Northern Hemisphere ecosystems
The correlation coefficients between the seasonal mean NDVI and the SPEI3 were calculated in a) early-growing season, b) mid-growing season and c) late-growing season.
