Summary

The use of acoustics for the study and interpretation of the atmospheric boundary layer is a useful scientific tool. The echosonde produces a record that can be visually integrated to produce a two-dimensional vertical profile (height as a function of time) of the planetary boundary layer over the echosonde site. From a continuous collection of this data, an acoustic climatology of the general area can be constructed. Routine data was collected over the Savannah River Plant site during certain periods at nights after a frontal passage and while the general area was under the influence of high atmospheric pressure. These data showed an abrupt transition from a laminar layered structure to a well-mixed atmospheric boundary layer.
