Rain Rate not reporting correctly **solved**

[Breno]

Just had a huge storm come through but the rain rate is not reporting correctly. See pictures to illustrate the problem. Rain rate hit over 300mm/h and was in the 100s for a long time but it never reported this to weather underground. Received 34.8mm in circa 20 minutes.

There are 3 meteobridges near me all exhibiting the same strange issue.

Rain rate is not the rain that has fallen the last 60 minutes, but an approximation of the current rain intensity to the hour.
Davis station reports very high rain rates when it is raining heavily. Your numbers are rather normal.
Apart from that, I suggest to forget about rain rate. It is guessing into the future, nothing to take seriously.

If you don't like this, tell Davis.

I like the way the Davis station reports instantaneous rain rate so I have no intention of "telling Davis". Are you saying the Meteobridge reinterprets the rain rate and reports differently instead of passing on what the vantage is reporting?

Rain rate is an odd one and not even Davis report this properly (that matches reality), so just because the Vantage is reporting rain rate does not mean it is correct or makes that much sense. You can test this yourself, set WeatherLink to record 1 minute intervals, click the rain bucket 5 times (0.2mm) for 1mm rain and if done in say 30 seconds then the Vue/VP2 console will display the amount of rain 1mm and a max rain rate of around the 120+/- 'ish mm/h mark depending on the bucket tipping rate. Watch the VP2 display and the rain rate will quickly decay then slowly decay to zero over about the next 15 minutes. Download WeatherLink and about the only record that makes any sense is the 1 minute interval when it rained, e.g 1mm @ 120mm/h etc (BTW Max rain rate reported by MBPro & Davis line up perfectly). WeatherLink for the next 15 minutes or so will actually show a rain rate value but the rain value will be zero.

So my question is how can the Vantage (in reality) rain rate be meaningful when it's not actually raining? Instantaneous rain rate is really a misconstrued idea as instantaneous rain rate and max rain rate at a point in time will be identical but from then on can not be so meaningful.

Nope it reports more or less identical to the Davis.

Ok, so weather underground must be dong the manipulation.
