 The distribution of stable isotopes in precipitation provides fundamental information about the partitioning of the global atmospheric water budget, and hence about key aspects of Earth's
climate, that cannot be discerned using other means. Although continuing demand exists for monitoring of isotopes in precipitation to define isotopic input functions for local hydrologic studies or for calibration of isotopic indicators of paleoclimate, awareness is also growing of the significant value of “snapshots” of the precipitation isotope fields as benchmark maps of the ongoing and dynamic evolution of the global water cycle. The Canadian Network for
Isotopes in Precipitation (CNIP) includes a 14-year dataset of composite monthly stable isotope measurements from six stations located in the Canadian high-latitudes.
This dataset provides unprecedented spatial and temporal coverage of the Canadian Arctic, which allows rigorous examination of isotope climate.
