Snow depth data from the sonic ranging sensor at the main meteorological station is now available for the period: 11/15/2014 to present. Snow depth data acquired from a Campbell Scientific SR50a is valuable for many research questions but can be noisy due to blowing snow or very low density snow. In order to produce the 3 hour data, we took samples every 5 minutes. We wrote a script that removed instances where there was more than a 1.0 cm of change in 5m, or if there was a grater than 0.5 cm change at the same time as a bad quality number from the instrument. Once a data point was removed, the filter was stricter for immediately following measurements to be included. We also manually corrected a handful of points. We then filled in the removed 5 minute points through linear interpolation and applied a 3 hour moving average.
