The Scintec RAE2 RASS Extension upgrades any Scintec Sodar SFAS, MFAS or XFAS to allow precise measurements of temperature profiles in the atmospheric boundary layer.
Temperature is retrieved by remotely measuring the speed of sound which depends on the temperature. This is done by doppler analysis of the frequency of radiowaves which have been reflected at acoustic waves emitted by the sodar.
RASS can replace towers, tethered balloons or radiosondes at a fraction of the operational costs. Compared to passive, thermal microwave techniques, RASS can precisely detect and locate even multiple inversions and has higher accuracy.
The Extended-Sweep Inversion technique (ESI) significantly increases the signal-to-noise ratio and allows for measurement ranges far wider than those of traditional systems.
The RAE2 is operated using the versatile software APRun with flexible configurability, extensive graphical display and output options, quality control features, statistical analysis tools and remote access support.
