Ben; Querel, Richard; Swart, Daan P.J. (Journal article; Peer reviewed, 2020)
      In this paper, we compare model calculations of ozone profiles and their variability for the period 1998 to 2016 with satellite and lidar profiles at five ground-based stations. Under the investigation is the temporal ...
    • The use of QBO, ENSO, and NAO perturbations in the evaluation of GOME-2 MetOp A total ozone measurements 

      Eleftheratos, Kostas; Zerefos, Christos S.; Balis, Dimitris S.; Koukouli, Maria-Elissavet; Kapsomenakis, John; Loyola, Diego G.; Valks, Pieter; Coldewey-Egbers, Melanie; Lerot, Christophe; Frith, Stacey M.; Søvde, Ole Amund; Isaksen, Ivar S A; Hassinen, Seppo (Journal article; Peer reviewed, 2019)
      In this work we present evidence that quasi cyclical perturbations in total ozone (quasi-biennial oscil lation – QBO, El Niño–Southern Oscillation – ENSO, and North Atlantic Oscillation – NAO) can be used as indepen dent ...
