The Scintec windRASS™ upgrades the sodar models SFAS or MFAS to work in radio-acoustic mode for precise measurements of both wind and temperature. This differs from conventional RASS where radio-acoustic sounding is used for temperature measurements only.

With windRASS™, acoustic and electro-magnetic beams are emitted in vertical and tilted directions. The electromagnetic waves are backscattered at the acoustic waves and a Doppler analysis is performed. Wind and temperature are derived via their influence on the speed of sound. windRASS™ is the first wind and temperature profiler that works anywhere, anytime. It is immune to ground clutter and ambient noise, making it a perfect solution for urban or industrial environments. Since windRASS™ does not depend on the existence of atmospheric turbulence, it operates at full performance in the marine boundary layer (coastal sites), foggy conditions or calm nights, each characterized by low turbulence levels. In addition, windRASS™ is not compromised by precipitation.

The Extended-Sweep Inversion technique (ESI) significantly increases the signal-to-noise ratio and allows for measurement ranges far wider than those of traditional RASS systems.

windRASS™ is operated using APRun with extensive graphical display options and remote access support.
