Deuterium and oxygen-18 in present-day precipitation: data and modelling

Abstract
The cycles of the water isotopic species (HDO and H2 18O) have been incorporated in three atmospheric General Circulation Models (GCMs) with the main objective of predicting the distribution of water stable isotopes in precipitation, The performances of those models are examined for present-day climate through a comparison with existing data available from the IAEA/WMO network established in 1961 and from other sources.
