A RASS Extension for LAP^® Series makes a Scintec LAP^® Series Radar a high-performance temperature profiler also. The RASS Extension for LAP^® Series consists of four acoustic sources which are placed around the antenna of the radar wind profiler. The acoustic sources emit sound waves into the vertical direction. The sound waves act as reflectors for the radio waves emitted from the radar wind profiler. The Doppler shift of the reflected radio waves depends on the travel speed of the sound waves and hence on the temperature within the volume comprising the propagating radar pulses. The operation software inverts the relationship and calculates the temperature versus height.

The RASS Extension for LAP^® Series is easily integrated into an existing LAP^® Series Radar Wind Profiler system. The vertical spacing of the temperature measurements corresponds to the spacing of the vertical wind measurements.

The RASS technology is unmatched when it comes to accuracy and reliability of temperature measurements and superior to passive radiometer sensors. Unlike radiometers, the RASS can resolve even complex temperature structures and does not require any regular calibration. This makes the RASS not only the most accurate and reliable but also the most cost-effective remote temperature measurement solution.
