A RASS Extension for FAS Series Sodars makes a Scintec FAS Series Sodar a high-performance temperature profiler also. The RASS Extension for FAS Series consists of four radio antennas which are placed around the acoustic antenna of the sodar wind profiler. The electromagnetic waves emitted by the radio antennas are scattered back by the sound waves emitted by the sodar antenna and are then received again by the radio antennas. There is a Doppler shift of the reflected radio waves which depends on the travel speed of the sound waves and hence on the temperature within the sensing volume. The operation software inverts this relationship and calculates the temperature versus height with high accuracy.
All RASS Extensions for Sodar can easily be integrated into existing FAS Series Sodar wind profiler systems. The vertical spacing of the measurement results corresponds to the vertical spacing of the sodar 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 device.
for SFAS, MFAS, XFAS
The Scintec RAE2 RASS Extension upgrades any Sodar model (SFAS, MFAS or XFAS) to allow precise measurements of temperature profiles in the atmospheric boundary layer.
for SFAS and MFAS
The Scintec windRASS Extension upgrades the Sodar models SFAS or MFAS to work in radio-acoustic mode for precise measurements of both wind and temperature.
