Abstract:
1-day age-depth resolution snow profile isotope data (dD, d18O, dxs, dxsln) from EastGRIP, Greenland. An age-depth model has been applied based on when peak monthly temperatures occur. The results of this modeled snow age are called ageDepth in this data set. In the absence of constrained peak temperatures, a mean accumulation for the relevant time period was used for the age-depth model.
