SPA-2 Snow Pack Analyzer
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 to calculate Snow Water Equivalent and density.

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.
