COMBLEISLAS

Within the ERC-funded project ISLAS, researchers from the University of Bergen, Norway, use the stable isotope composition of atmospheric water vapour and precipitation to obtain information about the sources and transport processes of water vapour within arctic weather systems. In particular, during cold-air outbreak conditions, evaporation and precipitation occur in close proximity within the study area. With evaporation studied at a single location (Ny Ålesund), ISLAS researchers want to be able to sample the resulting precipitation at several downstream locations. The ARMS COMBLE site is one of these locations, forming part of a network of precipitation-sampling stations that reach from Ny Ålesund, where water vapour isotope measurements are conducted near the surface, to Longyearbyen, Tromsø, Andenes, Ålesund, and Bergen. Daily precipitation samples, enhanced by more frequent sampling during intense observation periods, are to be conducted during a four-week period from 20 February to 20 March 2020. The contribution from the ARM COMBLE site will be a valuable contribution to understanding the spatial coherence of water isotope signals from arctic and extratropical weather systems.
