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.

interest.
