A summary overview about the types of lidar and their own applications on atmosphere detection is presented. Measurement of atmospheric aerosols by Mie lidar and Raman lidar is focused. The vertical profiles of aerosols in the atmosphere are retrieved. And at the same time, through analyzing aerosol vertical content distribution, the atmosphere boundary layer and the cloud are also observed. Al...

Measurements have been made in the wake of a model wind turbine in both a weakly unstable and a baseline neutral atmospheric boundary layer, in the EnFlo stratified-flow wind tunnel, between 0.5 and 10 rotor diameters from the turbine, as part of an investigation of wakes in offshore winds. In the unstable case the velocity deficit decreases more rapidly than in the neutral case, largely becaus...

The long term goals are: 1/ To understand the impact of complex coastal terrain and/or coastline orientation on the structure of the coastal marine atmospheric boundary layer (MABL); 2/ To study the effect on the atmospheric forcing of the coastal ocean, by the the local flow induced by the coastal terrain, including possible feedback mechanisms.; 3/ To understand the internal turbulence struct...

The atmospheric boundary layer (ABL) is “that part of the troposphere that is directly influenced by the presence of the earth’s surface, and responds to surface forcings with a timescale of about an hour or less” (Stull 1988). Mixing in the ABL can be driven by surface heating (free convection) and wind shear (forced convection). A capping inversion usually limits the depth of the daytime conv...
