There were no rain tips between Nov 20 and Dec 16, even during the snowstorm of Nov 23/24. There is data from the grass logger over this time. Rnet is the next field after rainr, and we have complete Rnet coverage. date/time MST tips Nov 20 13:32:30 61 Nov 20 13:37:30 189 ...zilch... Dec 16 01:07:30 1 After Dec 16, sporatic tips are seen - which looks reasonable - showing an accumulation of 5.3 mm between Dec 16 and Dec 25. I re-ran covar, with rainr by itself in a covar group, so it does not appear to be a software issue.
About 2 today, it started snowing. I would guess that we got at least 5cm by 5pm.
Snow depth gauge is 1.75 m above the grass, which agrees with the sensor output.
