7 Installation
7.1 Where should I install the SPA-2?
The selection of a suitable site is crucial to gain information of the snowpack that is representative
of the monitored area. Several aspects have to be considered when choosing a measurement site:
1. The selected site should be flat with no dips and rises.
2. The measurement spot should be representative of the monitored area.
3. There should be no boulders, trees, fences or other objects in the vicinity of the meas-
urement spot. Any obstacle can cause snow drift and thus affect the measurement results.
4. If feasible, the SPA-2 should be installed in the direction of the main wind. This minimizes dis-
turbances by snow drifts.
5. The site must be safe from avalanches.
