Determination of snowpack-properties can be very challenging as they vary significantly in space and time.
The SPA-2 snow pack analyzer measures the volumetric contents of ice and water within a snowpack, and together with the snow depth calculates the snow water equivalent (SWE) and snow density.
By measuring the complex impedance along multiple, 4.8 m long, ribbon-shaped sensors, the SPA-2 acquires area-averaged data about the snowpack at different depth.
Other than that, the snow height is precisely measured with the contact-free ultrasonic level sensor USH-9.
This sensor-combination provides an automatic measurement system to continuously monitor the snowpack development for hydrological, agricultural and other applications.
