      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 ...

    • Microphysical and optical properties of dust and tropical biomass burning aerosol layers in the Cape Verde region-an overview of the airborne in situ and lidar measurements during SAMUM-2
