The following links provide access to global grids of the hydrogen and oxygen isotope composition of precipitation and environmental waters in ArcGrid format. Use the links below to access downloadable file bundles archived with WinZip and/or 7-zip.
Files below include georeferenced ArcGIS raster coverages, ArcGIS 9 project files for map display, and complete metadata. The mean annual precipitation files also include shapefiles giving the location of all data stations and a raster of the 95% confidence intervals for the map predictions. The mean annual precipitation grids are updated versions of those produced in the Bowen and Revenaugh (2003) study, and the confidence interval grids are the original versions from that publication (new versions are being produced and should be available in early April). The growing-season grids are those reported in the Bowen et al. (2005) paper. Right-click (PC) or shift-click (Mac) to download files (~500 K each), extract to a working directory, and go!
|Mean annual precipitation, 20' x 20' resolution|
|Growing season precipitation, 20' x 20' resolution|
The files below offer complete ArcGIS grid sets giving annual and monthly precipitation isotope ratio estimates at 10' resolution. The WinZip archives contain the grid files only, stored in a geodatabase. These files provide the most complete and flexible content, but are also quite large (e.g., up to 20 Mb for the continental data sets, 77 Mb for the global grids).

The archive below includes maps of H and O isotope ratios and deuterium excess values for tap water in South Africa. The data layers are documented in the file readme.txt included in the the zip archive. The files were prepared using the method of Bowen et al. (2007) and a new data set of West et al. (in prep.)

The archives below contain maps of H and O isotope ratios for surface waters (rivers, streams) across the contiguous USA at 1 km x 1 km. These files represent the residual-corrected spatiotemporal model results of Bowen et al. (2011).
The archives below contain maps of estimated H and O isotope ratios for tap waters across most of the contiguous USA at 1 km x 1 km. These files contain the data presented in figure 4A and B of Bowen et al. (2007).
The archives below contain grids representing modeled 87Sr/86Sr values for bedrock, Sr derived from a combination of weathering of local bedrock, aerosols, and seaspray, and catchment-integrated river water dissolved Sr for parts of Central and South America and the Caribbean islands. These files contain data presented in figures 2 and 5B of Bataille et al. (2012) and from the application of the runoff model of Bataille and Bowen (2012) to the multi-source weathered Sr layer.
The archives below contain grids representing modeled 87Sr/86Sr values for bedrock, Sr derived from local bedrock weathering, and catchment-integrated river water dissolved Sr. These files contain data presented in figures 6B, 9A and 9B in Bataille and Bowen (2012).
