Fig. 5: Calibrated reconstruction of paleo-IVT using ensemble regression.

a The graph shows the calibration-in-time predictand. b The scatterplot shows the relation between Si/Al and IVT with points from 100 age ensemble members plotted with transparency and ensemble models plotted as partially transparent red lines. The right panel shows the distribution of the regression model (c) slope and (d) shows the intercepts, where vertical red lines indicate the 50th (solid), 2.5th, and 97.5th (dashed) percentiles. e The graph shows reconstructed IVT using age ensembles and regression model ensembles. The median estimate is shown as a solid black line and the 50 and 95% highest probability density regions are shown in dark and light gray.
