Global and regional maps of isotope ratios in precipitation

The figures linked below represent OIPC 3.0 estimates of monthly and annual average precipitation regionally and globally. They are intended as a visual and qualitative resource demonstrating the spatial distribution of water isotopes in precipitation. For quantitative use, I recommend working with the ArcGIS files available here.
