Measuring LWC over a perfectly controled snow sample volume
Based on capacitance technology and a concentric electrode design, the WISe device offers reliable LWC measurements over a perfectly controled snow sample volume.
LWC range
0-20 vol. %
Uncertainty
1 vol. %
Sampling volume
325 cm3
A reliable method based on the dielectric permittivity of snow in the MHz range
The WISe technology, developed in collaboration with Météo-France, relies on the relation between the liquid water content, the density and the permittivity of snow in the MHz range. The technique was validated against the well-established calorimetry method.
Application cases
- Snowmelt onset detection
- Snow avalanche forecasting
- Snow making quality assessment
- Radiative transfer calculations
- Remote sensing validation
