    • 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 ...

    • Potential of lidar backscatter data to estimate solar aerosol radiative forcing 

      Wendisch, Manfred; Mueller, D.; Mattis, I.; Ansmann, A. (2006-02-01)
      The potential to estimate solar aerosol radiative forcing (SARF) in cloudless conditions from backscatter data measured by widespread standard lidar has been investigated. For this purpose 132 days of sophisticated ...

    • 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 ...

    • Saharan Mineral Dust Experiments SAMUM-1 and SAMUM-2 : what have we learned? 

      Ansmann, Albert; Petzold, Andreas; Kandler, Konrad; Tegen, Ina; Wendisch, Manfred; Mueller, D.; Weinzierl, Bernadett; Mueller, Thomas; Heintzenberg, Jost (2011-09)
      Two comprehensive field campaigns were conducted in 2006 and 2008 in the framework of the Saharan Mineral Dust Experiment (SAMUM) project. The relationship between chemical composition, shape morphology, size distribution ...

    • 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 ...

    • Thermal IR radiative properties of mixed mineral dust and biomass aerosol during SAMUM-2 

      Köhler, Claas H.; Trautmann, Thomas; Lindermeir, Erwin; Vreeling, Willem; Lieke, Kirsten; Kandler, Konrad; Weinzierl, Bernadett; Gross, Silke; Tesche, Matthias; Wendisch, Manfred (2011-09-01)
      Ground-based high spectral resolution measurements of downwelling radiances from 800 to 1200cm-1 were conducted between 20 January and 6 February 2008 within the scope of the SAMUM-2 field experiment. We infer the spectral ...
