PPDIST uncertainty estimates for (a) the >0.5 mm d⁻¹ daily P occurrence and (b) the 15-year return-period daily P intensity. The uncertainty represents the spread of the ten cross-validation iterations. Supplement Fig. S5 presents an equivalent figure for the >0.1 mm 3 h⁻¹ P occurrence and the 15-year return-period 3-hourly P intensity.
