Abstract:
The dataset provides a 2.5-month record (December 6th 2023 – February 14th 2024) of the atmospheric water vapor isotopic composition at Concordia Station (Dome C), East Antarctica (-75.10°N, 123.35°E, 3233 m a.s.l.). The atmospheric water vapor isotopic composition is measured by two different laser spectrometers: a L2130-i analyser, manufactured by PICARRO Inc. (CRDS measurement technique) and a prototype version of the ProCeas H2O analyser, manufactured by AP2E Inc. (OF-CEAS measurement technique). The inlet of the instrumental set-up is sampling the atmosphere from 50 cm above the snow surface. The dataset provides the hourly-averaged calibrated measurements from both laser spectrometers. The datetime column is in UTC (UTC+8 for local datetime). The timestamp represents the start of the hourly-averaged period. The humidity (mixing ratio) data has been calibrated against an independent humidity measurement and is reported in ppmv. The isotope data has been calibrated for the isotope-humidity dependency and against the VSMOW-SLAP scale and is reported in delta-notation (in ‰).
