Hourly Rain Discrepancy

Post by krmidas »

According to my console, my station has recorded .37" of rain today.

The value for high hourly rainfall <#hourlyrainTH> displays as .33. That seems fine, as rain since midnight correctly shows 0.37.

But the value for this month's high hourly rainfall <#MonthHourlyRainH> is .49. And it also shows today's date.

Any ideas why I'm getting this discrepancy?

As you're not using the standard templates, please confirm that the web page is using the correct web tags, and that Cumulus itself is showing the same.

Assuming they are, please zip up the diags folder and attach it, along with your month.ini and today.ini files, and your July log file.

Steve,

I was looking through my Highest Hourly Rainfall records by month and can't understand why I have a discrepancy for the August value.

My all-time hourly rainfall is 1.1" ending at 17:34 on 12 August 2010. However, on the Monthly Extremes page for August it shows the Highest Hourly Rainfall as 0.28" ending 17:08 on 10 August 2011.

Using the Editor to retrieve values from both dayfile and logfiles it shows 0.28" on 10 Aug 2011 but this is clearly wrong.

I have double-checked the correct webtag is used. How would you suggest I correct the entry?

LATER: I have found the reason but don't know how best to proceed. The extra entries included in dayfile.txt which included hourly rainfall weren't present in Aug 2010. Manual edit required??
Cheers,
Ray, Cheshire.

The discrepancy is because the month-by-month all time records facility didn't exist in 2010 and the editor can only approximate retrospectively from data in the log files if the data is actually there. 'Highest hourly rain' wasn't in dayfile.txt in August 2010.
How would you suggest I correct the entry?
Use the monthly records editor?

Thanks Steve. All sorted. I'm always a bit nervous about editing data as I do it so infrequently.
Cheers,
Ray, Cheshire.
