Daily surface snow isotope ratios, Summit, Greenland, 2011-2014

The data set consists of surface snow stable isotope ratios (hydrogen and oxygen) based on samples collected approximately daily between June 2011 through June 2014 at Summit Station, Greenland (72 ºN, -38 ºW, 3209m). The samples and data were collected as part of the NSF funded project “Closing the Isotope Hydrology at Summit: Measurements of Source Regions, Precipitation and Post-deposition Processes”. The purpose of the data set is to complement observations of isotopic composition of water vapor isotope measurements made on the 50 meter tower alongside ancillary measurements of meteorology, turbulence and hydrometeor microphysics.
