    • Aerosol and dynamical contributions to cloud droplet formation in Arctic low-level clouds 

      Motos, Ghislain; Freitas, Gabriel; Georgakaki, Paraskevi; Wieder, Jörg; Li, Guangyu; Aas, Wenche; Lunder, Chris Rene; Krejci, Radovan; Pasquier, Julie Thérèse; Henneberger, Jan; David, Robert Oscar; Ritter, Christoph; Mohr, Claudia; Zieger, Paul; Nenes, Athanasios (Peer reviewed; Journal article, 2023)
      The Arctic is one of the most rapidly warming regions of the globe. Low-level clouds and fog modify the energy transfer from and to space and play a key role in the observed strong Arctic surface warming, a phenomenon ...

    • Monitoring aerosol optical depth during the Arctic night: Instrument development and first results 

      Mazzola, Mauro; Stone, Robert S.; Kouremeti, Natalia; Vitale, Vito; Gröbner, Julian; Stebel, Kerstin; Hansen, Georg Heinrich; Stone, Thomas C.; Ritter, Christoph; Pulimeno, Simone (Peer reviewed; Journal article, 2024)
      Moon-photometric measurements were made at two locations in the Arctic during winter nights using two different modified Sun photometers; a Carter Scott SP02 and a Precision Filter Radiometer (PFR) developed at PMOD/WRC. ...

    • Re-evaluation and Homogenization of Aerosol Optical Depth Observations in Svalbard (ReHearsol). RCN Project No: 311250/E40 - ReHearsol Final Report 

      Hansen, Georg H.; Zielinski, Tymon; Pakszys, Paulina; Ritter, Christoph; Gilardoni, Stefania; Eleftheriadis, Konstantinos; Kouremeti, Natalia; Mateos, David; Herrero, Sara; Kazadzis, Stelios; Mazzola, Mauro; Stebel, Kerstin (NILU report;3/2022, Research report, 2022)
      The aim of this project was to collect, integrate and analyse observations of climate-relevant aerosol parameters (aerosol optical depth (AOD), Ångstrøm exponent (AE), black carbon (BC)) in and around Svalbard. These ...
