      As the third most important greenhouse gas (GHG) after carbon dioxide (CO2) and methane (CH4), tropospheric ozone (O3) is also an air pollutant causing damage to human health and ecosystems. This study brings together ...

    • Clean air policies are key for successfully mitigating Arctic warming 

      von Salzen, Knut; Whaley, Cynthia; Anenberg, Susan C.; Van Dingenen, Rita; Klimont, Zbigniew; Flanner, Mark G.; Mahmood, Rashed; Arnold, Stephen R.; Beagley, Stephen; Chien, Rong-You; Christensen, Jesper H.; Eckhardt, Sabine; Ekman, Annica M. L.; Evangeliou, Nikolaos; Faluvegi, Greg; Fu, Joshua S.; Gauss, Michael (Peer reviewed; Journal article, 2022)
      A tighter integration of modeling frameworks for climate and air quality is urgently needed to assess the impacts of clean air policies on future Arctic and global climate. We combined a new model emulator and comprehensive ...

    • Contributions of Nordic anthropogenic emissions on air pollution and premature mortality over the Nordic region and the Arctic 

      Im, Ulas; Christensen, Jesper H.; Nielsen, Ole-Kenneth; Sand, Maria; Makkonen, Risto; Geels, Camilla; Anderson, Camilla; Kukkonen, Jaakko; Lopez-Aparicio, Susana; Brandt, Jørgen (Journal article; Peer reviewed, 2019)
      This modeling study presents the sectoral contributions of anthropogenic emissions in the four Nordic countries (Denmark, Finland, Norway and Sweden) on air pollution levels and the associated health impacts and costs over ...

    • The influence of residential wood combustion on the concentrations of PM2.5 in four Nordic cities 

      Kukkonen, Jaakko; Lopez-Aparicio, Susana; Segersson, David; Geels, Camilla; Kangas, Leena; Kauhaniemi, Mari; Maragkidou, Androniki; Jensen, Anne; Assmuth, Timo; Karppinen, Ari; Sofiev, Mikhail; Hellén, Heidi; Riikonen, Kari; Nikmo, Juha; Kousa, Anu; Niemi, Jarkko; Karvosenoja, Niko; Sousa Santos, Gabriela; Sundvor, Ingrid; Im, Ulas; Christensen, Jesper H.; Nielsen, Ole-Kenneth; Plejdrup, Marlene S.; Nøjgaard, Jacob Klenø; Omstedt, Gunnar; Andersson, Camilla; Forsberg, Bertil; Brandt, Jørgen (Peer reviewed; Journal article, 2020)
      Residential wood combustion (RWC) is an important contributor to air quality in numerous regions worldwide. This study is the first extensive evaluation of the influence of RWC on ambient air quality in several Nordic ...
