Pepijn; Wagner, Thomas; Wittrock, Folkard; Gonzalez, Margarita Yela; Zehner, Claus (Peer reviewed; Journal article, 2021)
      This paper reports on consolidated ground-based validation results of the atmospheric NO2 data produced operationally since April 2018 by the TROPOspheric Monitoring Instrument (TROPOMI) on board of the ESA/EU Copernicus ...

    • Impact of 3D cloud structures on the atmospheric trace gas products from UV–Vis sounders – Part 1: Synthetic dataset for validation of trace gas retrieval algorithms 

      Emde, Claudia; Yu, Huan; Kylling, Arve; Van Roozendael, Michel; Stebel, Kerstin; Veihelmann, Ben (Peer reviewed; Journal article, 2022)
      Retrievals of trace gas concentrations from satellite observations are mostly performed for clear regions or regions with low cloud coverage. However, even fully clear pixels can be affected by clouds in the vicinity, ...

    • Impact of 3D cloud structures on the atmospheric trace gas products from UV–Vis sounders – Part 2: Impact on NO2 retrieval and mitigation strategies 

      Yu, Huan; Emde, Claudia; Kylling, Arve; Veihelmann, Ben; Mayer, Bernhard; Stebel, Kerstin; Van Roozendael, Michel (Journal article, 2022)
      Operational retrievals of tropospheric trace gases from space-borne spectrometers are based on one-dimensional radiative transfer models. To minimize cloud effects, trace gas retrievals generally implement a simple cloud ...

    • Satellite validation strategy assessments based on the AROMAT campaigns 

      Merlaud, Alexis; Belegante, Livio; Constantin, Daniel-Eduard; Den Hoed, Mirjam; Meier, Andreas Carlos; Allaart, Marc; Ardelean, Magdalena; Arseni, Maxim; Bösch, Tim; Brenot, Hugues; Calcan, Andreea; Dekemper, Emmanuel; Donner, Sebastian; Dörner, Steffen; Dragomir, Mariana Carmelia Balanica; Georgescu, Lucian; Nemuc, Anca; Nicolae, Doina; Pinardi, Gaia; Richter, Andreas; Rosu, Adrian; Ruhtz, Thomas; Schönhardt, Anja; Schuettemeyer, Dirk; Shaiganfar, Reza; Stebel, Kerstin; Tack, Frederik; Vajaiac, Sorin Nicolae; Vasilescu, Jeni; Vanhamel, Jurgen; Wagner, Thomas; Van Roozendael, Michel (Peer reviewed; Journal article, 2020)
      The Airborne ROmanian Measurements of Aerosols and Trace gases (AROMAT) campaigns took place in Romania in September 2014 and August 2015. They focused on two sites: the Bucharest urban area and large power plants in the ...

      Brenot, Hugues; Theys, Nicolas; Clarisse, Lieven; Van Geffen, Jos H.G.M.; Van Gent, Jeroen; Van Roozendael, Michel; Van Der A, Ronald J.; Hurtmans, Daniel; Coheur, Pierre-François; Clerbaux, Cathy; Valks, Pieter J.M.; Hedelt, Pascal; Prata, Alfredo; Rasson, Olivier; Sievers, Klaus; Zehner, Claus (Journal article; Peer reviewed, 2014)

    • Trends in polar ozone loss since 1989: potential sign of recovery in the Arctic ozone column 

      Pazmiño, Andrea; Goutail, Florence; Godin-Beekmann, Sophie; Hauchecorne, Alain; Pommereau, Jean-Pierre; Chipperfield, Martyn P.; Feng, Wuhu; Lefèvre, Franck; Lecouffe, Audrey; Van Roozendael, Michel; Jepsen, Nis; Hansen, Georg H.; Kivi, Rigel; Strong, Kimberly; Walker, Kaley A. (Peer reviewed; Journal article, 2023)
      Ozone depletion over the polar regions is monitored each year by satellite- and ground-based instruments. In this study, the vortex-averaged ozone loss over the last 3 decades is evaluated for both polar regions using the ...
