Extended Data Fig. 2: The long-term effects of drought on the start of growing season (SOS) during 1982-2015.
From: Drought legacies delay spring green-up in northern ecosystems

Spatial distribution of cumulative changes between next year’s SOS (SOSnext) and current year’s SOS (SOScurrent), normalized by the average over 34 years, when droughts occurred (a) and not occurred (b). Insets show the area fraction of SOS delayed (orange) or advanced (blue) by drought.
