Simultaneous horizontal and vertical acoustic sounding of the atmospheric boundary layer

Abstract

Some preliminary results from a series of experiments of simultaneous horizontal and vertical acoustic sounding of the atmosphere are described and discussed. The novel horizontal configuration offers some potential for investigating thermal plume motion and characteristics within the boundary layer. It could also be of use in assessing the importance of excess attenuation in quantitative acoustic sounding.

Effects of stability on the profiles of vertical velocity and its variance in katabatic flow

“…Moulsley et al (1979) took advantage of the much smaller size of their minisodar, relative to conventional systems, t o mount the instrument on a tower and point horizontally. This orientation enables one to sample the horizontal dimensions of thermals and, to some extent, the distribution of thermals.…”
