Telemetering precipitation gages for remote areas

The precipitation gage described is designed especially for use in remote areas where precipitation occurs as rain, snow, or a combination of both, and where accumulation may be 100 inches or more between visits, which may be made only once or twice a year. Design emphasis has been on simplicity and reliability in order to provide a system which can be maintained with a minimum use of highly skilled personnel. A gas bubble system is provided to assist in mixing the precipitation with an initial charge of ethylene glycol to inhibit freezing and help melt incoming snow. Towers are designed for maximum strength combined with lightweight and easy installation. The radio communication system which provides on-call operation and uses solar cells to trickle charge the battery power supply is described. Operating problems and site selection are discussed.
