The ISOARC project: From source to sink – Monitoring the isotopic fingerprints of Arctic moisture
In order to constrain the isotopic fingerprint of the Arctic hydrological cycle, a new generation of Picarro water isotope analyzers using CRDS (cavity ringdown spectroscopy) is used to monitor the isotopic composition of atmospheric water vapour at different sites. Since July 2015, within the ISOAR...
