Abstract: We describe a ground-based system that provides quasi real-time measurement and collection of snow-water equivalent (SWE) data in remote settings. The system is significantly cheaper and easier to deploy than current methods and is more robust to terrain and snow bridging effects. The system also enjoys several possible remote data recovery solutions. Compared to current infrastructure using existing technology, our system features will combine to allow more sites to be installed for the same cost and effort, in a greater variety of terrain, enabling data collection at improved spatial resolutions. The system integrates a new computational architecture with new sensor technologies. Our computational architecture is based on wireless sensor networks, comprised of programmable, low-cost, low-powered nodes capable of sophisticated sensor control and remote data communication. Our sensor technology works by measuring attenuation of electromagnetic radiation, an approach that is immune to snow bridging and significantly reduces sensor footprints.
