| Zusammenfassung |
| A network of 45 spatially distributed time-lapse cameras was used to carry
out a continuous observation of snow processes and snow cover properties
throughout three mid-latitude medium elevation mountain catchments in hourly
intervals during the winter seasons of 2010/2011 and 2011/2012. A simple
technical modification was conducted to enable the deployment of the
standard digital cameras in any location. Image analysis software was
applied to extract information about snow depth, surface albedo and canopy
interception from the digital images. Furthermore, the distributed design of
the camera network made it possible to identify the elevation of the snow
rain interface for any precipitation event which is very helpful for the
interpretation of winter flooding events resulting from snow melt. Exemplary
data for all these analyses is presented to show the potential fields of
application of this innovative approach. Study results prove that the
application of digital time-lapse photography is an appropriate technique to
observe the spatial distribution and temporal evolution of seasonal snow
covers in a mountainous environment. |
