| description | This paper illustrates measurements carried out by the
Raman lidar BASIL in the frame of the HD(CP)<sup>2</sup> Observational Prototype
Experiment (HOPE), revealing the presence of a clear-air dark band phenomenon
(i.e. a minimum in lidar backscatter echoes) in the upper portion of the
convective boundary layer. The phenomenon is clearly distinguishable in the
lidar backscatter echoes at 532 and 1064 nm, as well as in the particle
depolarisation data. This phenomenon is attributed to the presence of lignite
aerosol particles advected from the surrounding open pit mines in the
vicinity of the measuring site. The paper provides evidence of the phenomenon
and illustrates possible interpretations for its occurrence. |
