      Frank, Lukas; Jonassen, Marius Opsanger; Skogseth, Ragnheid; Vihma, Timo Pekka (Journal article; Peer reviewed, 2023)
      The Isfjorden region at the west coast of Spitsbergen is the most easily accessible area in the Svalbard Archipelago, making it a perfect outdoor laboratory for Arctic research. Due to its location in the high Arctic ...
    • Evaluation of three numerical weather prediction models for the Weddell Sea region for the Austral winter 2013 

      Jonassen, Marius Opsanger; Nygård, Tiina; Vihma, Timo Pekka (Journal article; Peer reviewed, 2021)
      It is widely recognized that numerical weather prediction (NWP) results for the Antarctic are relatively poor compared to the mid-latitudes. In this study, we evaluate output from three operational NWP systems: the ECMWF, ...

    • Present Temperature, Precipitation, and Rain‐on‐Snow Climate in Svalbard 

      Wickström, Siiri; Jonassen, Marius Opsanger; Cassano, John J.; Vihma, Timo Pekka (Journal article; Peer reviewed, 2020)
      The Svalbard Archipelago has undergone rapid warming in the recent decades leading to warmer and wetter winter conditions. This study relates the present (2013–2018) 2 m temperature, precipitation, and rain-on-snow (ROS) ...
