δ18O water isotope in the iLOVECLIM model (version 1.0) – Part 1: Implementation and verification
A new 18O stable water isotope scheme is developed for three components of the iLOVECLIM coupled climate model: atmospheric, oceanic and land surface. The equations required to reproduce the fractionation of stable water isotopes in the simplified atmospheric model ECBilt are developed consistently...
