*Flat Array Sodar MFAS*
The Scintec MFAS is a versatile acoustic profiler for the measurement of wind and turbulence up to 1000 m above the ground.  The operation is based on the reflection of acoustic pulses at temperature inhomogeneities in the air with subsequent doppler analysis.  The instrument can replace towers, tethered balloons or radiosondes at a fraction of the operational costs.  With its small size and low weight, the system can be easily transported and installed. Its low power consumption also facilitates the unmanned operation in remote areas.

MFAS can be further upgraded by RASS Extensions (RAE2 and windRASS) for precise measurements of temperature profiles. In addition to temperature, the windRASS model also performs wind measurements with the combined radio-acoustic measurement technique, which ensures a robust measurement that works anywhere and anytime.
