The snow gauge in the 3D-PAWS system combines a MaxBotix HRXL-MaxSonar-WRLS ultrasonic sensor with an external MB79XX HR-MaxTemp temperature correction sensor to deliver precise snow depth measurements. The ultrasonic sensor provides accurate, real-time distance readings to the snow surface, while the external temperature sensor compensates for variations in the speed of sound caused by changing air temperatures. This dual-sensor approach significantly improves measurement accuracy, especially during periods of rapid temperature fluctuation, and is recommended for weather station and snowpack monitoring applications.
