      Tsekeri, Alexandra; Amiridis, Vassilis; Lopatin, Anton; Marinou, Eleni; Giannakaki, Eleni; Pikridas, Michael; Sciare, Jean; Liakakou, Eleni; Gerasopoulos, Evangelos; Duesing, Sebastian; Corbin, Joel C.; Gysel, Martin; Bukowiecki, Nicolas; Baars, Holger; Engelmann, Ronny; Wehner, Birgit; Kottas, Michael; Mamali, Dimitra; Kokkalis, Panagiotis; Raptis, Panagiotis I.; Stavroulas, Iasonas; Keleshis, Christos; Müller, Detlef; Solomos, Stavros; Binietoglou, Ioannis; Mihalopoulos, Nikolaos; Papayannis, Alexandros; Stachlewska, Iwona S.; Igloffstein, Julia; Wandinger, Ulla; Wandinger, Ulla; Dubovik, Oleg; Goloub, Philippe (2018-04-13)
      Aerosol absorption profiling is crucial for radiative transfer calculations and climate modelling. Here, we utilize the synergy of lidar with sun-photometer measurements to derive the absorption coefficient and single ...

    • Linear polarization signatures of atmospheric dust with the SolPol direct-sun polarimeter 

      Daskalopoulou, Vasiliki; Raptis, Panagiotis I.; Tsekeri, Alexandra; Amiridis, Vassilis; Kazadzis, Stelios; Ulanowski, Zbigniew; Charmandaris, Vassilis; Tassis, Konstantinos; Martin, William (2023-10-12)
      Dust particles in lofted atmospheric layers may present a preferential orientation, which could be detected from the resulting dichroic extinction of the transmitted sunlight. The first indications were provided relatively ...

    • Measurement report: Balloon-borne in-situ profiling of Saharan dust over Cyprus with the UCASS optical particle counter 

      Kezoudi, Maria; Tesche, Matthias; Smith, Helen; Ulanowski, Zbigniew; Amiridis, Vassilis; Mueller, Detlef; Weinzierl, Bernadett; Tsekeri, Alexandra; Baars, Holger; Dollner, Maximilian; Estellés, Víctor; Bühl, Johannes (2021-05-05)
      This paper presents measurements of mineral dust concentration in the diameter range from 0.4 to 14.0 μm with a novel balloon-borne optical particle counter, the Universal Cloud and Aerosol Sounding System (UCASS). The ...

    • Monitoring dust particle orientation with measurements of sunlight dichroic extinction 

      Daskalopoulou, V.; Raptis, I.P; Tsekeri, Alexandra; Amiridis, Vassilis; Kazadzis, S.; Ulanowski, Zbigniew; Metallinos , S.; Tassis, K.; Martin, Bill (2021-09-29)
      Alignment of irregularly shaped dust aerosols leading to linear dichroism has been reported in atmospheric layers. The present study intents to quantify the excess linear polarization of direct solar radiation propagating ...

    • Retrieval of ice-nucleating particle concentrations from lidar observations and comparison with UAV in situ measurements 

      Marinou, Eleni; Tesche, Matthias; Nenes, Athanasios; Ansmann, Albert; Schrod, Jann; Mamali, Dimitra; Tsekeri, Alexandra; Pikridas, Michael; Baars, Holger; Engelmann, Ronny; Voudouri, Kalliopi-Artemis; Solomos, Stavros; Sciare, Jean; Gross, Silke; Ewald, Florian; Amiridis, Vassilis (2019-09-09)
      Aerosols that are efficient ice-nucleating particles (INPs) are crucial for the formation of cloud ice via heterogeneous nucleation in the atmosphere. The distribution of INPs on a large spatial scale and as a function of ...

    • Studies on mineral dust using airborne lidar, ground-based remote sensing, and in situ instrumentation 

      Marenco, Franco; Ryder, Claire; Estelles, Victor; Segura, Sara; Amiridis, Vassilis; Proestakis, Emmanouil; Marinou, Eleni; Tsekeri, Alexandra; Smith, Helen R.; Ulanowski, Zbigniew; O'Sullivan, Debbie; Brooke, Jennifer; Pradhan, Yaswant; Buxmann, Joelle (2018-04-13)
      In August 2015, the AER-D campaign made use of the FAAM research aircraft based in Cape Verde, and targeted mineral dust. First results will be shown here. The campaign had multiple objectives: (1) lidar dust mapping for ...

    • The unprecedented 2017-2018 stratospheric smoke event : Decay phase and aerosol properties observed with the EARLINET
