Cumulus Support

Sorry, and thanks...

this is a fixed? version....

The diags folder, please?

Your rain counter jumped from zero (?) to 143.8, hence your high rain rate. It looks like your counter is zero all the way back to the beginning of October, until it suddenly jumped up to 143.8 at 17:30 today. I'm afraid i have no idea how that could have happened.

13/10/12,17:26,9.3,75,5.1,0.7,0.7,225,0.0,0.0,1013.0,139.2,19.9,54,0.7,9.3,9.3,0,0,0.00,0.00,8.0,14,0.0,225,0.0
13/10/12,17:30,10.0,75,5.8,0.7,0.7,225,143.8,0.0,1013.1,139.2,20.0,54,0.7,10.0,10.0,0,0,0.00,0.00,8.8,11,0.0,225,0.0

sorry

pc crash - lovely

that would be when I took it down and cleaned it out cos it did not seem to be working...

so if I set this to zero...... (must have missed that one) :/

Your current rain counter is 139.2. So if you set that one to zero, the 139.2 will cause a large rain rate calculation. Did you edit oct12log.txt and set all of the counters (except the last one) to zero? is that where all of the zeros came from? That's guaranteed to screw up all kinds of things. I've clearly failed to explain anything, sorry. I think I have to give up now. Sorry.

I don't think my sensor has worked since october, was all zero until I cleaned it out.

I then edited data cos it had increased the amount by 12mm (127.2 to 139.2), I noticed where the 12mm had come in, but did not do the total rainfall originally, so set those values back from 139.2 to 127.2.

well, I will figure it out

No, I'm sorry, I'm tired and I was looking at the wrong column. Let me look at the data again and I'll see if I can see what's going on.

The large rain rate occurred because you set the rain counter in the file back:

13/10/12,17:25,9.3,75,5.1,0.7,0.7,225,0.0,0.0,1013.0,127.2,19.9,54,0.7,9.3,9.3,0,0,0.00,0.00,8.0,15,0.0,225,0.0
13/10/12,17:26,9.3,75,5.1,0.7,0.7,225,0.0,0.0,1013.0,139.2,19.9,54,0.7,9.3,9.3,0,0,0.00,0.00,8.0,14,0.0,225,0.0
13/10/12,17:30,10.0,75,5.8,0.7,0.7,225,143.8,0.0,1013.1,139.2,20.0,54,0.7,10.0,10.0,0,0,0.00,0.00,8.8,11,0.0,225,0.0

So as far as Cumulus was concerned, there was a sudden jump of 12 mm at 17:26, hence the high rain rate. You basically just moved your extra 12mm from earlier in the day to 17:26, so you're now back where you were when the problem first occurred.

If you want to edit the rain counter values retrospectively, you have to set them relative to the current counter, not what it should have been without the extra rain, i.e. set them all to 139.2 for zero rain.

Oh, ok. So if the Total Rainfall Counter is 127.2 for the whole month, where is cumulus getting the 12mm difference? another record which still reads 139.2?

Thanks

oh my lord I see it now... in today.ini there is a start value of 139.199996948242... It is all falling into place

Thanks for your help - very much appreciated

139.2 is the value of the rain counter in your station now; that's where Cumulus is getting it from.

but changing that value to 127.2 does not reset everything it seems.... doh - I think I am creating a mess....

You can't change that value, that's the whole point. It's the value in the rain gauge. All you can do is retrospectively modify the previous rain counter values to take account of the current value, so that all of the values are once again consistent. That's how the 'today's rain' editor works. It rewrites history by pretending that the start of day counter was something other than what it actually was at the time.
