Dust Intrusion Influence on Atmospheric Boundary Layer Using Lidar Data
The PBL (Planetary Boundary Layer) is the lowest part of the troposphere and plays an important role in our everyday live. Diverse applications of boundarylayer meteorology require better understandings of the PBL. The depth of the PBL varies greatly in space and time, but knowledge of the depth of PBL aid in the validation of parameterizations of the PBL in general circulation models and improve our abilities to model the coupling between the atmosphere and the Earth’s surface. Lidar (Light Detection and Ranging) measurements provide useful information on the structure of PBL. The aim of this paper is to study the influence of dust intrusion on mixed layer. To detect the mixed layer depth we used the gradient method on two cases: dust intrusion and background aerosol. We discuss the results using complementary information as synoptic maps, backtrajectories and radio soundings. Similar results for the PBL height obtained from lidar data and radio sounding showed in this paper demonstrates the importance of the remote sensing measurements in atmosphere.
