About the DEOS Snow Monitoring System

Real-time snow depth measurements are provided by the Delaware Environmental Observing System (DEOS) to the State of Delaware through funding from the Delaware Department of Transportation (DelDOT) for the Snow Removal Reimbursement Program. Snow measurements are now being taken over official National Weather Service snowboards. The snow monitoring stations directly measure snow depth, which is processed every five minutes to produce snow accumulation data.


DEOS Snow Monitoring Station

Snow depth is measured using a sonic ranging depth sensor, which is shown in the image to the above. This sensor sends a sonic (sound) signal from its base to the surface below. This signal is then reflected from the surface to the sensor where an air temperature-calibrated distance-to-surface measurement is calculated. This distance is then subtracted from the initial height of the sensor above the ground to yield a snow depth measurement. The accuracy of this sensor is +/- 1 cm (approximately 0.3937 in.). Each snow depth measurement undergoes a quality control procedure that checks for instrumentation error and data integrity according to the manufacturer's recommendations.
