Fig. 3: Coral multi-proxy correlation with observed summer rainfall.

a Crossplot with annual 1-σ uncertainty. b Reconstructed rainfall from coral (blue, 1943-1984) and the instrumental record (orange, 1950–2020). The calibration set is the overlapping period 1950–1984. Blue shading is the annual 1-σ uncertainty and orange shading is the standard deviation of observed rainfall estimates among sites for a given season.
