Description:
The Earth's hydrological cycle is fundamentally linked with the climate system. The atmospheric heat engine is driven primarily by energy exchanges associated with the condensation of water. As a result, variations in isotopic ratios of oxygen (16O,18O) and hydrogen (1H,2H) contained in the water molecule can be used to extract information on the history of a water parcel. Indeed, present day isotope patterns are found to be correlated with present day climatic and hydrological processes. Recent advances have been made to integrate the stable isotopes of water into ocean, atmosphere, and land hydrological models by tracking the isotopic composition of reservoirs and fluxes and simulating fractionation processes. This has provided a potentially powerful tool for validation, sensitivity analysis, and inverse modeling of water cycling processes.
Currently, expertise in the development of tracer-capable models is limited to a few research and government organizations. Wider application of isotope tracer diagnostics in regional climate models for water resources and climate change studies requires that expertise be shared between tracer modeling experts and the modeling community. The seminar is intended to improve the current situation by offering expert technical instruction and training to a limited number of skilled modelers who can develop tracer models for their home institutions.
