more negative d18O reflects higher rainfall amounts

The age model was computed in MATLAB® based on a cubic interpolation between the 230Th ages, its distance from the stalagmite top, and the corresponding dating errors. Multiple age models are produced to account for the analytical uncertainties and the errors in the location of each drill hole (assumed to be <0.2 mm). Therefore, multiple iterations of the age model were calculated assuming a normally distributed deviation from the 230Th age and the standard deviation given by the error range (Monte Carlo simulation). Iterations with reversals were dropped and an ensemble of 100 age models was created (i.e., all reversals could be removed within the error margins). In this model the median age in the distribution was used for each point.

Rainfall amount and d18O of rainfall depend on the position of the ITCZ and frequency of ENSO
