Water vapour isotopes analyser calibrated data from Samoylov station

This data set contains two years of calibrated continuous in situ water vapour isotopic observations conducted since July 2015 in the east-Siberian Lena delta, at the research station on the Samoylov Island (72°22'N, 126°29'E). The temporal resolution of this data set is of 1 hour. The measurements have been performed with a Cavity RingDown Spectrometer located in a heated container outside the main station. The ambient air inlet is located at 5 m above the ground level. Calibration is achieved via the measurement of liquid water standards injected with a custom-made system including a vapourizer and a dew-point generator (bubbler).
