Global climatology, monthly, daily precipitation isotope dataset, 1947–2024 (NetCDF and GeoTIFF)

This dataset provides global gridded stable water isotope data for precipitation and atmospheric water vapor from 1 September 1947 to 31 March 2024 at a spatial resolution of 1.25°. Precipitation variables include δ18O, δ2H, and d-excess in both bias-corrected and uncorrected versions, while water vapor variables include δ18O and δ2H. Daily and monthly data are provided in NetCDF format, together with monthly and mean annual precipitation climatologies in GeoTIFF format. Isotope values are expressed in per mille (‰).
