| Summary: | Water isotope measurements (i.e. δ18O, δD, and d-excess) of snow and atmospheric vapor were made to document evolution of snow surface water isotopes, with implications for ice core analysis and climate models. Laboratory experiments were used to measure changes in the snow surface in a controlled setting influenced only by sublimation, and field experiments were used to measure changes in the snow surface in a natural setting. Laboratory data includes experiments from 2017-2019, completed at the University of Copenhagen and the University of Colorado Boulder. Eight 4-6 day sublimation experiments were completed, in which 4-6 boxes were filled with well-mixed snow and one box was removed and measured each day. Data includes daily mass and water isotope measurements for snow samples at 0.5 cm intervals from 0-4 cm for all experiments. One experiment includes hourly water isotope and humidity measurements for vapor at 28 and 32 cm above the snow surface, and temperature at 4 cm below the snow surface, the snow ... |
