Snow board was not in place, but I was able to measure the snow depth on the screen in the NovaLynx funnel area. Snow was also caught in the funnel of the CoCoRaHS gauge and was melted to get the equivalent value.
Hydreon did not record the snow, start/stop is approximate from heated Davis VP2 data on WU, but this tends to lag actual times. |

Weighing method using Escali scale resulted in 0.417 inch. I poured out the measuring tube into the outer cylinder to get this mass. Just a test before snow season.
VP2=0.36" Note: Wind from SSE during rain event may have caused rain shadow for Davis gauge.
NovaLynx=0.44". Gage was recalibrated on 11/3 using low-flow orifice. Recent results are showing improvement.

I'll report the "stick" measurement, since I didn't get outside last evening prior to rain and melting. Snow is extremely wet and slushy. Melt from gauge was 0.72". Windy conditions prevailed so this is probably an under-catch. Core from snowboard taken from average area. Note agreement with rangefinder estimate. |

Melt from gauge is 0.18"; VP2=0.14; URF=11.89"; Depth is an average of four measurements, combined with delta increase on URF from yesterday. Significant drifting and blowing of snow. Snowboard depth is an average of four quadrants of the board. Core taken at representative area. Observation is earlier today due to personal reasons. Checked additional areas later this morning. New snow depths vary considerably from as low as 3 inches to as much as 6 inches. 4 - 5" seems typical. Snow board caught a bit of a drift so the amount reported may be higher than typical of other areas. |
