Water stable isotopic composition of precipitation at Concordia Station (Dome C), East Antarctica (2017-2021)

The data set provides a five-year record (2017-2021) of the water stable isotopic composition of precipitation samples collected daily at Concordia Station (Dome C), East Antarctica (-75.10°N, 123.35°E, 3233 m a.s.l.). The samples are collected every day at 2 AM UTC all-year round on a raised platform (1m from the surface), 800m upwind of the main station. The water stable isotopic composition of the samples is measured at the Ca' Foscari University of Venice, Italy, with PICARRO laser spectrometers. The data is reported with delta-notation (in ‰) with respect to the Vienna Standard Mean Ocean Water (VSMOW). In addition, the data set provides the weight of each precipitation sample collected, converted to SWE (mm w.e.).
