Extended Data Fig. 3: Seasonal changes of PR −EP and NDVI.
From: Increase in plant reliance on past precipitation associated with greening and drying
Monthly \({P}_{R}-{E}_{P}\) and NDVI during 1982 − 2021 in the two-dimensional space, with the reordered months of the year as x-axis and aridity index as y-axis. The months were reordered by starting with the wettest months indicated by \({P}_{R}-{E}_{P}\) (a), and the greenest months, indicated by NDVI (b). The late growing season is marked with white slashes, which starts with the month with maximum NDVI and ends when it decreases to half of the amplitude. The wet-to-dry transitional period is marked with white backslashes, which starts with the month with maximum cumulative \({P}_{R}-{E}_{P}\) and lasts for 3 months.
