- •
Recent tufa δ18O reveal seasonal and decadal climate changes in NE Iberia.
- •
δ18O calcite-derived Tw fit regional and local air temperature trends through time.
- •
Calculated Tw can be biased by discharge and rainfall isotopic composition changes.
- •
δ13C calcite reflects both exceptional discharge events and in-aquifer recharge.
- •
Together, this is relevant to climate inferences from isotopes in carbonate records.
