Fig. 14. A traditional thermodynamic model of an unstable atmospheric boundary layer. A logarithmic layer near the surface blends into a constant-temperature mixed layer that extends to the top of the boundary layer. A stable atmosphere with a temperature inversion acts as a lid to the vertical motions of the air below. A lidar signal showing the height of the boundary layer with time is shown on the right. Reds are highest particulate concentrations and blues are lowest. The thermodynamic diagram is shown to the left, scaled to the lidar signal.
