Get this from a library. Theory and application of a Radio-Acoustic Sounding System (RASS). [Richard J Lataitis; Wave Propagation Laboratory.]. A radio acoustic sounding system (RASS) is a system for measuring the atmospheric lapse rate using backscattering of radio waves from an acoustic wave front to measure the speed of sound at various heights above the ground.

This is possible because the compression and rarefaction of air by an acoustic wave changes the dielectric properties, producing partial reflection of the.

Radio acoustic sounding systems A radio acoustic sounding system is used to measure the virtual temperature profile in the lower troposphere. VDI Environmental Meteorology - Ground-Based Remote Sensing Of Of Temperature - Radio-Acoustic Sounding Systems (Rass).

where C s (m s-1) is the speed of sound, R is the gas constant of air, γ (= c p /c v) is the ratio of the specific heats of air, and T v is the virtual temperature in degrees Kelvin. Using this relation, the vertical profile of sound speed can be converted to a profile of virtual temperature.

The RASS technique depends on close matching of the acoustic wavelength to half the radar wavelength.
