ECHAM6-wiso nudged simulation water isotopes and precipitation for the period 1990-2020 at the EastGRIP drilling location, Greenland

This model dataset contains output produced with the isotope-enabled atmosphere GCM ECHAM6-wiso at T127L95 spatial resolution, nudged to the ERA-5 reanalysis product. The 6-hourly model output is provided for the period 01/1990-12/2020 for the grid cell containing EastGRIP drilling location in Greenland, centered at 75.27N, -36.57 E.

The provided variables are:

        d18O_vapor: delta value for ¹⁸O (‰) in the vapor of the lowest atmospheric layer (ECHAM level 95).
        dD_vapor: delta value for H₂ (D) (‰) in the vapor of the lowest atmospheric layer (ECHAM level 95).
        aprt: total precipitation (mm water equivalent per month)
        d18O_precip: delta value for ¹⁸O (‰) in the precipitation
        dD_precip: delta value for H₂ (D) (‰) in the precipitation
