Abstract:
Stable water vapor isotopologue data (~1Hz) from the 2m level above snow surface. The cavity ring-down spectroscopy instrument used was a Picarro L-2140i. The data was corrected for the humidity-isotope response of the instrument and the measurements referenced to the VSMOW-SLAP scale. The estimated precision is 0.23 ‰ for d18O and 1.4‰ for dD following Steen-Larsen et al. (2013). The measurements span a period from 25.05.2019-29.07.2019. The measurement site was co-located with the EastGRIP ice core site in the accumulation zone of the Greenland Ice Sheet.
