    • Desert dust aerosol air mass mapping in the western Sahara, using particle properties derived from space-based multi-angle imaging 

      Kahn, Ralph; Petzold, Andreas; Wendisch, Manfred; Bierwirth, Eike; Dinter, Tilman; Esselborn, Michael; Fiebig, Marcus; Heese, Birgit; Knippertz, Peter; Mueller, D.; Schladitz, Alexander; Hoyningen-Huene, Andwolfgang Von (2009-02)
      Coincident observations made over the Moroccan desert during the Sahara mineral dust experiment (SAMUM) 2006 field campaign are used both to validate aerosol amount and type retrieved from multi-angle imaging spectroradiometer ...

    • Dust mobilization and transport in the northern Sahara during SAMUM 2006 - a meteorological overview 

      Knippertz, Peter; Ansmann, Albert; Althausen, Dietrich; Mueller, D.; Tesche, Matthias; Bierwirth, Eike; Dinter, Tilman; Mueller, Thomas; Von Hoyningen-Huene, Wolfgang; Schepanski, Kerstin; Wendisch, Manfred; Heinold, Bernd; Kandler, Konrad; Petzold, Andreas; Schuetz, Lothar; Tegen, Ina (2009-02)
      The SAMUM field campaign in southern Morocco in May/June 2006 provides valuable data to study the emission, and the horizontal and vertical transports of mineral dust in the Northern Sahara. Radiosonde and lidar observations ...

    • Retrieval of aerosol optical thickness for desert conditions using MERIS observations during the SAMUM campaign 

      Dinter, Tilman; Von Hoyningen-Huene, Wolfgang; Burrows, John P.; Kokhanovsky, Alexander; Bierwirth, Eike; Wendisch, Manfred; Mueller, D.; Kahn, Ralph; Diouri, Mohammed (2009-02)
      Approximately 30% of the land surface is arid, having desert or semi-desert conditions. Aerosol originating from these regions plays a significant role in climate and atmospheric chemistry of the atmosphere. Retrieving ...

    • Solar radiative effects of a Saharan dust plume observed during SAMUM assuming spheroidal model particles 

      Otto, Sebastian; Bierwirth, Eike; Weinzierl, Bernadett; Kandler, Konrad; Esselborn, Michael; Tesche, Matthias; Schladitz, Alexander; Wendisch, Manfred; Trautmann, Thomas (2009-02-02)
      The solar optical properties of Saharan mineral dust observed during the Saharan Mineral Dust Experiment (SAMUM) were explored based on measured size-number distributions and chemical composition. The size-resolved complex ...

    • Spectral surface albedo over Morocco and its impact on radiative forcing of Saharan dust 

      Bierwirth, Eike; Wendisch, Manfred; Ehrlich, Andre; Heese, Birgit; Tesche, Matthias; Althausen, Dietrich; Schladitz, Alexander; Mueller, D.; Otto, Sebastian; Trautmann, Thomas; Dinter, Tilman; von Hoyningen-Huene, Wolfgang; Kahn, Ralph (2009-02)
      In May-June 2006, airborne and ground-based solar (0.3-2.2 mu m) and thermal infrared (4-42 mu m) radiation measurements have been performed in Morocco within the Saharan Mineral Dust Experiment (SAMUM). Upwelling and ...

    • Vertical profiling of convective dust plumes in southern Morocco during SAMUM 

      Ansmann, Albert; Tesche, Matthias; Knippertz, Peter; Bierwirth, Eike; Althausen, Dietrich; Mueller, D.; Schulz, Oliver (2009-02)
      Lifting of dust particles by dust devils and convective plumes may significantly contribute to the global mineral dust budget. During the Saharan Mineral Dust Experiment (SAMUM) in May-June 2006 vertical profiling of dusty ...
