RASS
Radio Acoustic Sounding System

The Radio Acoustic Sounding System (RASS) is an active ground-based acoustic sounder that provides profiles of virtual temperature. It uses radar techniques to measure acoustic disturbances to derive the virtual temperature. They are typically used in conjunction with radar wind profilers (RWPs) and operate at frequencies of 915 MHz and 1290 MHz. RASS has a sampling rate of around 5 to 15 minutes, a 150 m vertical resolution, and a 60 m horizontal resolution.
