      For the first time, colocated dual-field of view (dual-FOV) Raman lidar and Doppler lidar observations (case studies) of aerosol and cloud optical and microphysical properties below and within thin layered liquid water ...
    • Dust and smoke transport from Africa to South America : Lidar profiling over Cape Verde and the Amazon rainforest 

      Ansmann, Albert; Baars, Holger; Tesche, Matthias; Mueller, D.; Althausen, Dietrich; Engelmann, Ronny; Pauliquevis, Theotonio; Artaxo, Paulo (2009-06-02)
      Quasi-simultaneous vertically resolved multiwavelength aerosol Raman lidar observations were conducted in the near field (Praia, Cape Verde, 15 degrees N, 23.5 degrees W) and in the far field (Manaus, Amazon basin, Brazil, ...
    • PollyNET - a network of multiwavelength polarization Raman lidars 

      Althausen, Dietrich; Engelmann, Ronny; Baars, Holger; Heese, Birgit; Kanitz, Thomas; Komppula, M.; Giannakaki, Eleni; Pfuller, Anne; Maria Silva, Ana; Preiler, Jana; Wagner, Frank; Rascado, Juan Luis; Pereira, Sergio; Lim, Jae Hyun; Young Ahn, Joon; Tesche, Matthias; Stachlewska, Iwona S. (SPIE, 2013-10-22)
      PollyNET is a growing global network of automatized multiwavelength polarization Raman lidars of type Polly (Althausen et al., 2009). The goal of this network is to conduct advanced remote measurements of aerosol profiles ...
