GPS Snow Depth Probe

The GPS snow depth probe is similar to the automatic snow depth probe, but also records a GPS position (as well as NEMA codes indicating the quality of the position). Accuracy of the GPS is ±10 m absolute, and ±2 m relative on repeated surveys. Using this probe, an operator can walk across a snow-covered landscape and in several hours produce a detailed transect of snow depths. Data on 2 meter spacing over several kilometers can be obtained in just a few hours. Data is downloaded to a computer at the end of a day or several days. The probe can remember several thousand depths.
