Re: New rain rate calculation
Observations with build 583, installed and started about 15:07:
It's drizzling outside.
When Cumulus registers a bucket tip it is added to today's rain.
After a short delay I get a rain rate of 3.6 (or 4.5) mm/hour, and that lasts for 5 minutes.
Then rain rate goes back to zero.
Is that what you intended?
(By the way: no change in rain rate graph)

Re: New rain rate calculation
Yes, that sounds about right, assuming it was just the one tip and then no more in the next 5 minutes.dane wrote:After a short delay I get a rain rate of 3.6 (or 4.5) mm/hour, and that lasts for 5 minutes.

Annoyingly, I saw that problem coming, and thought I had fixed it. Inadvertently having two variables with the same name meant that I hadn't really fixed it.(By the way: no change in rain rate graph)
Thanks,
Steve

Re: New rain rate calculation
Yes: only 1 tip about every 20 minutes now.
(But we've had 34.5 mm since midnight

Re: New rain rate calculation
Probably not much help, but I have just installed 583 to replace 575. There has been some rain today, mixed in with the odd bit of light snow. My rainfall rate guage shows three separate spikes each individually rising to a peak of (precisely ???) 0.14 inches.

Re: New rain rate calculation
If they're on the graph, they'll be from the history data, because of the bug that Ib spotted. But what you're seeing is the sort of thing that the new algorithm will produce.harrym1byt wrote:Probably not much help, but I have just installed 583 to replace 575.

Re: New rain rate calculation
Experiences with build 587:
stopped Cumulus at about 20:00 yesterday.
Installed 587 and started Cumulus today.
And rain graphs look "interesting": continuous rain rate of 1.3 mm from 20:00 to restart time.
And rain today restarted at 20:00 until midnight, then restarted at midnight.

Re: New rain rate calculation
I think in fixing the 'normal running' rain rate, I have broken the 'history data' rain rate. I will check.
It looks like your station's total rain count went back to zero at 20:00. You could check this by looking at the Dec08log.txt file.

Re: New rain rate calculation
No: total rain count in dec08log.txt looks OK: continues to grow from 282.3 at 20:00 to 285.6 now.

Could you let me have the last few files from your Diags folder, please?

Re: New rain rate calculation
Build 589 behaves beautifully: 3.6 mm for 5 minutes for 1 tip.
Thank you.
Thank you.

Re: New rain rate calculation
Great - thanks. It could have been better, if I could have got the 'intelligent' method to work. But I think this will do for now.

Re: New rain rate calculation
Hi Terry, looks like you didn't get enough to get a tip. If you mean this morning, a few lightish showers here which (I'm only three miles from Terry, btw) gave me 0.3mm. Perhaps you only got 0.29
Probably not Cumulus.

Re: New rain rate calculation
584 seemed to be misbehaving in that once it saw rain, the line on the Rate graph stayed high and level for a long time -
0.14 inches appeared on the graph at just before 04:00 today and the line stayed at 0.14 until 18:00, when it suddely fell back to zero. I know there has been some rain today, but it has not been continuous, not obviously at exactly the same rate for 14 hours. Cumulus was not running during any of that period, if it makes a difference?
Now updated to 589.
