Extended Data Fig. 4

Return periods T (yr), diagnosed from EF (a) and SIF (b). To diagnose T, a range of alternative values of T are screened and the corresponding range of values SCWDXT are compared to SdEF SdSIF) within 1∘ grid cells (resolution of maps shown here). The best matching T was retained for each gridcell, yielding a global distribution of TEF (TSIF). The bottom panel shows the distribution of diagnosed return periods T (mean of TEF and TSIF) within bins of the Compound Topography Index60 (c) and forest cover fractions (MOD44B62) (d). Boxes represent the interquartile ranges of binned values (Q25, Q75), and whiskers cover Q25 − 1.5(Q75 − Q25) to Q75 + 1.5(Q75 − Q25). Numbers of data points per bin are given above boxes.
