Hourly Rainfall Run Amok

Post by jtrost »

Within the last few days, the Record Hourly Rainfall/Last Hour Rainfall has been showing impossible numbers. I may have a daily total of just a few hundredths of an inch of rain but the Last hour and record Hourly rainfall will show 4 or 5 inches. Of course this then replaces the real maximum hourly, so my records are lost. I installed the latest version of Cumulus, but it had no effect. The next day an impossible number displayed in Last Hour.

It's a common problem with Fine Offset stations, the total rain counter does odd things occasionally. Cumulus has 'spike removal' settings for rain rate and hourly rain, on the calibration screen. See the FAQ and the wiki for information on correcting rainfall figures: http://wiki.sandaysoft.com/a/FAQ#My_sta ... _figure.29
