During a 5-week measurement campaign (ISLAS2020) in February and March 2020, we collected measurements of the stable isotope composition in atmospheric water in Svalbard and along the Norwegian coast. This included discrete collecting of precipitation at Ny-Ålesund, Longyearbyen, Tromsø, Andenes, Ålesund, and Bergen. Additionally, Ny-Ålesund hosted the primary field experiment of the campaign, with a cavity ring-down spectrometer (CRDS) installation, measuring the in-situ stable isotope composition of the ambient air at three deployment sites. At two of these sites, we performed near-surface vertical profiling of stable water isotopes, to quantify the isotopic gradients above the snow-covered tundra and the open fjord water. These profiles were collocated with high-resolution temperature measurements from fiber-optic distributed sensing methods. At each of the three CRDS deployment sites, automated weather stations logged the ambient meteorological conditions. In addition to the precipitation collected at ...
