Paleotemperature Records of the Last Glacial Maximum from Noble Gases in Groundwater

This data set includes noble gas measurements and modeled recharge temperatures from 32 separate groundwater studies, each analyzed using the same consistent framework and set of noble gas temperature models (CE, PR, and OD models). Along with noble gas data and modeled temperatures are site information (coordinates, recharge elevation), groundwater age data, modern recharge temperatures, other model outputs (excess air, fractionation), and uncertainties for all variables of interest. These data were used to estimate LGM-Late Holocene temperature differences from each site and, together, for the large-scale low-latitude, low-elevation land surface.
