A recent Euro News TV report called - "Mapping Out The Future of
Alpine Glaciers" features a Campbell Scientific weather station in
use
in Northern Italy. When you see the challenging environments the
station endures and the journey required to access it one can see
why
reliability and low power are so important in these solar powered,
autonomous systems.
The camera shows a number of sensors including the SR50A sonic snow
depth sensor; all sensors are measured by the CR3000 datalogger in
the
enclosure which also processes and stores the data onboard and
controls the telecommunications to transmit data back to the control
centre.
See the report here http://bit.ly/adCTnB - I hope you all find it of
interest.

.... Thanks! indeed it was: I would have liked to see more of the
'innards' of the system, i.e., a demonstration of how the snow
depth/thickness is actually measured, some idea of how accurate these
particular sensors are & how they cope when high-altitude weather is
'extreme' and the snow levels are fluctuating dramatically - but I
realise this was for a general audience.
