Cumulus Support

Is there a webtag to display the highest yearly rainfall recorded since station records began.

No, but has been discussed before. And see this, raised yesterday: https://cumulus.hosiene.co.uk/tracker.php?p=1&t=248

Sorry Steve, hadn't seen that.

I think that the last time this came up, I cheekily suggested that it could be done semi-automatically with a bit of javascript, pre-loaded with the current record.

Out of interest I totted up the rainfall here for the last 3 calendar years...

2010 - 27.61" (701mm)
2011 - 33.87" (860mm)
2012 (to 28th) - 39.32" (999mm)

plus 0.2" (5mm) and counting today.

The 2012 total is 43% more than that of 2010.

It can also been seen by using the NOAA style reports.

I have a mismatch in my Rainfall This Year webtag and the NOAA annual rainfall totals. I notice you do too John. I'm trying to work out why. The following are totals to midnight 28 Dec.

My Rainfall This Year webtag total is 39.65".
The NOAA total is 39.46".
If I add the total amounts of Rain Today in Dayfile.txt using Microsoft Access I get 39.32".

I have 37 days where the total rainfall was 0.01". I know these are discounted as rain days in NOAA but possibly not in the Rainfall This Year and NOAA totals.

I've used Access to calculate my 2012 monthly totals and they all match the NOAA total except December which is 0.1" higher in NOAA than the actual. So that NOAA total should be 39.36". That makes it 0.29" lower than the Rainfall This Year webtag total of 39.65" suggesting the 0.01" values are not included in the NOAA totals but are added to the Rainfall This Year total. The final difference of 0.05" could be due to rounding.

Assuming the Rainfall This Year and NOAA annual total should match is this something I should raise as a possible bug?

I've just checked 2010 and 2011 rainfall using Dayfile.txt in Access against the NOAA totals and they are spot on for each month and the annual total. 2012 also matches except the current month - December - which shows 4.54" instead of 4.4" in the NOAA total.

Ray, your site currently shows:

Today: 0.27
This month: 4.81
This year: 39.73

Taking off today's figure gives:

This month: 4.81-0.27 = 4.54
This year: 39.73-0.27 = 39.46

Your NOAA report for this month shows a total of 4.54
Your NOAA reports for this year shows a total of 39.46 (and 4.54 for Dec).

That all looks consistent to me?

Hi Steve,

Ah, so Rainfall This Month and Rainfall This Year also includes today's amounts. I hadn't appreciated that. I thought those were only updated once a day just after midnight. Mystery solved, thanks.

Or a quick query to your SQL database

Indeed.

The javascript or SQL thingy are waaaaayyyyyy beyond me Ill stick with the NOAA data

I didn't want to start a new topic as the question I have relates to total yearly rainfall.
The yearly total that is recorded on my station on wunderground is 1248.7mm, link here; http://www.wunderground.com/weatherstat ... hspan=year

Yet Cumulus is reporting a different total 1407.0mm

Thanks for any replies,

I have no idea how WU calculates its data, sorry. Cumulus calculates the annual total by adding the daily totals in dayfile.txt. The rain data sent to WU is the total so far during the day, so if any uploads at the end of the day are missed for whatever reason, then the WU figure will presumably be too low.
