Extended Data Fig. 9: Effects of mean climate change (climatic extreme excluded) on the spring-summer growth linkage.
From: Diminishing carryover benefits of earlier spring vegetation growth
This is the same as Fig. 1a, except that years with dry/hot extremes are excluded from the analysis. Asterisks denote years with statistically significant correlation (p < 0.05) using two-sided t test. The extreme years are defined as those with the standardized precipitation evapotranspiration index (SPEI of at least one spring/summer months falling 1.5 standard deviation below its climatology. We used a 3-month SPEI dataset based on the CRU climatic data to capture short-term water deficits (https://spei.csic.es/database.html).
