I have a question regarding dry days.
As soon as a day reaches even 0.1 mm, it is no longer considered dry except that often these 0.1 or 0.2 mm are caused by dew. I know that dew is a type of rain, but in concrete terms, can't we consider these values as negligible over 1 day to interrupt the number of days?
Just a detail ^^
thanks!
In french :
J'ai une question concernant les journées de sécheresse.
Dès qu'une journée atteint ne serait-ce que 0,1 mm, on ne la considère plus comme sèche sauf que souvent ces 0,1 ou 0,2 mm sont provoquées par la rosée. Je sais que la rosée est un type de pluie mais concrètement, mais ne peut on pas considérer ces valeurs comme négligeables sur 1 journée pour interrompre le nombre de jour ?
Juste un détail ^^
merci !

Re: longest Dry Period
When CUtils was created it was based on the Davis weather station which has a low limit of measurement of rain of 0.2 mm which appeared to be OK for the limit of counting as a rain day. The Ecowitt WH40 however has 0.1 mm as a limit of measurement. As CUtils counted larger than 0.0 as a rain day I recently changed that to larger than or equal to 0.2. That seems to work fine. So just upgrade to the latest version and that is solved I think.Benji60 wrote: ↑Mon 02 May 2022 6:03 am I have a question regarding dry days.

The 0.1 measurement does appear in the YADR (it needs some kind of recognition ) but is not counted as a rain day.
