Seasonal 1° mean canopy LAI change at different climate zones. We applied a Welch's t test to examine whether the observed mean LAI change is different from 0 (seasons with P < 0.05 have their legend item in bold). The strongest seasonal variation of canopy LAI was found in the southern Amazon, in contrast to the western Amazon, which showed no statistically significant change in LAI.
