Hi Arnold,
thanks for your fast reply.
Coincidence - I was just checking if ClimGen could do the job, but couldn't find out how.
Could you give me an advice here?
Regarding precipitation and monthly data - probably a misunderstanding - but I pretty much assume that data are the sum of precipitation in that respective month, and not daily data averaged over a month. (Anyway, one could be converted into the other easily.)
Best regards,
Rolf

Hi Rolf,
A weather generator (i.e. SIMMETEO, CLIMGEN, WGEN, etc.) can disaggregated your monthly data into daily values. However, I am not sure if they can handle monthly sums because the usual input to weather generators are monthly averages.
Hope this help.
Best regards,
Arnold

Dear all,
I have historic rainfall data (1940-1985) as monthly sums, which I would
like to disaggregate to obtain approximate daily data to use it for crop
modeling. I wonder if anybody of you ever has done this, if there is
standard procedure or (even better) software that could do
that for me.
Of course, I have more recent (approximately 30 years) daily records of
the same region. So I could do all kind of supporting statistical
analyses.
Best regards,
Rolf
