You'll need to be tough to beat those, as you'll be tempted to put the aircon on!

[I can loosely verify the daily rain total, as our old-style manual rain gauge filled up, was emptied - I was silly enough to go out into it - and nearly filled up again.]
Hourly rain: 67.3mm (see pic nest post)
I did beat your Daily at 90.8mm but can't beat 231.3mm! (not yet at least)

Also I see Steve says that the rain rate is calculated differently and thus Davis naturally get a higher rain rate compared to Fine Offset.
So, for Fine Offset, High Rain rate 121.1mm/hr.
Sorry, wrote on the picture as a WH....it's a WS-1081 Fine Offset (Sinometer).

Re: Mine’s Bigger than Yours
Ah...well done Bob, I know I'm gonna beat that since I've only been going a month. I'm attaching a 24hr chart of the rainfall rate so that maybe we can compare our Ws-1081 to the Davis Pro's and others. It seems the DP get really high readings that Steve seems to understand. Any one with a DP with a high rain rate care to supply a graph. Is a 24hr graph to long? Should we make it 1 hr, what do you think?tjaliwalpa wrote:Beat that (just) in dry Karoonda:MickinMoulden wrote: So, for Fine Offset, High Rain rate 121.1mm/hr.

Re: Mine’s Bigger than Yours
The main difference between the Davis rain rate (as calculated by the station) and the FO rain rate (calculated by Cumulus) is the period over which the rate is calculated. The Davis rain rate is calculated using the time between adjacent tips, and so a very brief (less than a minute), high intensity shower can produce a very high rain rate. The Cumulus rate is simply the average over the last five minutes, so requires a more sustained level of rainfall to achieve similar rates.MickinMoulden wrote:It seems the DP get really high readings that Steve seems to understand.

The rate from a Davis can change (up and down) so quickly that it may not even register on the 1-minute sampling period of the Cumulus graphs, or retrospectively, looking at data from the logs. For example, my all-time high rainfall rate as measured by my Davis is 295.4 mm/hr at 17:18 on 24th March 2009. Here's the graph plotted from my logs at that time. Not very impressive.

Re: Mine’s Bigger than Yours
On the graph it measures to 7. Is that 7 inches per hr (177.8mm/hr)?steve wrote:The main difference between the Davis rain rate (as calculated by the station) and the FO rain rate (calculated by Cumulus) is the period over which the rate is calculated.

Also, could you add the rain amount with your graph, I think it may help to compare. I actually used a ruler to get the steepest gradient from the rain being recorded, and my measurements mirrored what was recorded for the rain rate.

Here's the graph with the rain total included. It was only a small amount of rain, but it fell very quickly. Because of the 5-minute logging interval, the gradient isn't steep, but presumably at some point it was falling very heavily for a short period, hence the high rate.Also, could you add the rain amount with your graph, I think it may help to compare.

Re: Mine’s Bigger than Yours
Ha Ha That's funny. Imagine what I would (and others with a FO) would have recorded with a Vantage Pro? At least with the Cumulus Graph we can compare apples with apples.steve wrote:No, it's millimetres!MickinMoulden wrote:On the graph it measures to 7. Is that 7 inches per hr (177.8mm/hr)?
I can tell you when it rains here when your driving, and hard, you have to halve your speed (ok we should actually pull over) because you can only see the car in front of you for the 1/2 second after the wiper blades sweep past. Even with the other cars headlights/tail lights on, all the cars dissapears from view (this is during the middle of the day).
Actual visability would be 100 to 200 meters if you're standing on your varandah.

Re: Mine’s Bigger than Yours
But the 7 doesn't really mean anything, it's just the figure that the rate had got down to at the point where Cumulus took its snapshot. Had I been logging at 1-minute intervals, then the 295.4 figure may well have appeared in the log. This just demonstrates the deficiency in Cumulus 1 of its 'snapshot' style of logging.Ha Ha That's funny.
It's hard to say; possibly exactly the same as you have recorded now. It's not simply a case of saying that the Davis rate is always higher than the Cumulus FO rate. You just need a shorter period of heavy rain with a Davis to get a high rate.MickinMoulden wrote:Imagine what I would (and others with a FO) would have recorded with a Vantage Pro?

Re: Mine’s Bigger than Yours
The best you can do with an FO station is a reading every 48 seconds. I've definitely seen quick bursts of rain lasting for shorter periods.

Re: Mine’s Bigger than Yours
I can fully understand what you are saying, however, how is it you can say the above that itsteve wrote:But the 7 doesn't really mean anything, it's just the figure that the rate had got down to at the point where Cumulus took its snapshot.

(from 295 to 7) then......the 7 doesn't really mean anything, it's just the figure that the rate had got down to

.........you say that mine would be excactly the same even if I had a VP? Mathmatically it is "possible", however you can get 295 on your VP but Cumulus says 7 but yet you can't believe that mine at 121 couldn't be extremly higher on a VP let alone any different.
Let's forget what both our rain rates are for a minute. You register 0.6mm at some point in 5 minutes, then 0, then 0 then 0.2mm at some point in 5 minutes. I on the otherhand got 7mm at some point in 5min, then 7, then 3 then 3 then 10.1. Which would you think had the heaviest rain rate? You measured 0.6mm in 5 min and at some point got 295.4mm/hr, or the equivalent of 0.6mm falling in 7.3 sec and I had 10.1mm fall at some point in 5 minutes, yet you find it hard to believe that if I had a VP recording the rain rate that it wouldn't be higher than 295, and go on to say that it be "possibly exactly the same".
But we will never know.
As we are all Cumulus users, my point was, that using the Cumulus graph is the only way we can compare fairly and I believe that it should be noted that VP and others PWS should have their separate records.
