Abstract:
For the observation of high-resolution spatial and temporal snow dynamics in mountains remote sensing is an important tool. Satellite-data are commonly used with a high spatial but low temporal or low spatial but high temporal resolution. Therefore, it is not possible to analyse rapid small-scale variations of the snow cover caused by snowfall, re-deposition or melting and its relationship with topography.
To monitor and to analyse the variation of snow cover distribution two digital cameras (MetSupport?) are positioned on opposite ridges at 2200 m a.s.l. and 2400 m a.s.l. They are taking daily images from the opposite, north-west and south-east-facing slope. In a following step, these images are georeferenced using “Georeferencing Terrestrial Photography” developed by J. CORRIPIO and classified in ENVI. The influence of climatic and topographic parameters on the temporal dynamics of snow accumulation, re-distribution and depletion is finally analysed by statistical methods.
