Snow Cover Monitoring
The snow depths maxima were 15.7 m, 6.1 m, 13.4 m, 7.6 m and 14.2 m recorded in five winter seasons between 2000 and 2004

Snow depth (m)
about 310 000 m3 of snow
almost 150 000 m3 of snow water equivalent
Snow Cover Monitoring
Analysis of snow depth on botanical transects for computation of relation between snow and vegetation
Snow Cover Monitoring
Combination of snow cover distribution and vegetation cover
GNSS and Environmental Protection
GPS is very helpful for the environment
