discrepancy value of rain rate

[actioman]

Yesterday I noticed there is a discrepancy in the amount of rain rate recorded and shown on the graphs?





It happens to anyone else? Is it a bug?

As you can see in my previous weather station, a fine-offset one, this was more accurate!?





Thank you in advance for any help.

Does this help?

Yes indeed helps.
What I did not know was that the same applied to the rain rate data.

Thank you Mark for your help.

Yet another question about the same topic.

Before with a fine-offset weather station whenever recorded 0.3 mm of rainfall (which was its least), marked a 3.5 mm of rain-rate, now with the Davis when it registers the 0.2 mm of rain does not mark anything in the rain-rate graph.

This is normal?

Thanks!

Yes, it's the way Davis stations calculate rain rate - by the time between tips. So it takes two tips within 15 minutes before it shows a rain rate.

If you want to know more about how your station calculates some of its data (including the answer to your rain rate question), there's a useful document from Davis here: http://davisnet.com/product_documents/w ... iables.pdf

No, I'm afraid not; I'm hoping they come in the post this morning. I'm still having to use some glasses that I'm not used to
