Isotope mass-balance modeling of the modern and paleo-water of Lake Zóñar. We use the methodological approach described in ref.35. Parametrization of the model used a suit of conservative hydrological parameters that cover the modern and potential conditions in the past (Supplementary table S5). The model satisfies simultaneously the δ18O, δD, d-excess and 17Oexcess of the measured lake water. During the IRHP, the model implies slightly drier climate (relative humidity of ~ 55–60% compared to ~ 65–70% for modern conditions) and higher evaporation-to-inflow ratio (~ 1.4–1.6 compared to 0.6–1.0 for modern conditions) during the IRHP, suggesting more evaporated lake conditions and drier climate.
