I think the question should also be asked, is it better to show no measurable precipitation of any type (shutting the sensor off) or having a somewhat skewed measurement in the interim?
As an example, during the last snow/sleet/ice event here in N.Y., my Sky showed a somewhat high reading relative to my 2 area airports for this same event. My Sky showed .69" vs .54" and 52" for the 2 area airports in fairly close proximity to me. Given that my Davis showed 0.00" precipitation (not heated) and no other area PWS indicated any precip either, I’m not unhappy with the results. This is the first event of this type since I’ve had my Sky and I wasn’t sure what to expect.
Was I lucky that my measured amount was as close as it was to the actual ‘official’ measurement? Who knows, it was the first even of this type since I had installed my Sky.
So at least IMO, I’d rather have somewhat of an overestimate than a ‘non-event’ reported by a non-heated tipping bucket system. The tipping bucket would have (and did) indicate that no precipitation event had occurred.
With that said I can certainly see others feeling differently.
