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
