    • Arctic hydroclimate variability during the last 2000 years: Current understanding and research challenges 

      Linderholm, Hans W.; Nicolle, Marie; Francus, Pierre; Gajewski, Konrad; Helama, Samuli; Korhola, Atte; Solomina, Olga; Yu, Zicheng; Zhang, Peng; D'Andrea, William J.; Debret, Maxime; Divine, Dmitry V; Gunnarson, Björn E.; Loader, Neil J.; Massei, Nicolas; Seftigen, Kristina; Thomas, Elizabeth K.; Werner, Johannes; Andersson, Sofia; Berntsson, Annika; Luoto, Tomi P.; Nevalainen, Liisa; Saarni, Saija; Väliranta, Minna (Peer reviewed; Journal article, 2018-04-10)
      Reanalysis data show an increasing trend in Arctic precipitation over the 20th century, but changes are not homogenous across seasons or space. The observed hydroclimate changes are expected to continue and possibly ...

    • Assessing non-linearity in European temperature-sensitive tree-ring data 

      Ljungqvist, Fredrik Charpentier; Thejll, Peter; Björklund, Jesper; Gunnarson, Björn E.; Piermattei, Alma; Rydval, Miloš; Seftigen, Kristina; Støve, Bård; Büntgen, Ulf (Journal article; Peer reviewed, 2020-02)
      We test the application of parametric, non-parametric, and semi-parametric calibration models for reconstructing summer (June–August) temperature from a set of tree-ring width and density data on the same dendro samples ...

    • European warm-season temperature and hydroclimate since 850 CE 

      Ljungqvist, Fredrik Charpentier; Seim, Andrea; Krusic, Paul J.; Gonzalez-Rouco, Jesus Fidel; Werner, Johannes; Cook, Edward R.; Zorita, Eduardo; Luterbacher, Jürg; Xoplaki, Elena; Destouni, Georgia; Garcia-Bustamante, Elena; Aguilar, Camilo Andres Melo; Seftigen, Kristina; Wang, Jianglin; Gagen, Mary H.; Esper, Jan; Solomina, Olga; Fleitmann, Dominik; Büntgen, Ulf (Journal article; Peer reviewed, 2019)
      The long-term relationship between temperature and hydroclimate has remained uncertain due to the short length of instrumental measurements and inconsistent results from climate model simulations. This lack of understanding ...
