ymonadd (Abort): Month index 5 already allocated!
Added by Mikko Strahlendorff over 4 years ago
I am trying to bias adjust a 51 member ensemble:
seq 0 50 | parallel -j 16 --compress --tmpdir tmp/ cdo --eccodes ymonadd era5-ecsf_2000-2019_t+sw+sd-monthly-eu-bias.grib -remapbil,era5-eu-grid -selvar,2d,2t,rsn,sd,stl1,swvl1,swvl2,swvl3,swvl4 ens/ec-sf_$year${month}_all-24h-eu-{}.grib ens/ec-bsf_$year${month}_t+sw+sd-24h-eu-{}.grib
it fails with an error that I don't understand. year=2020 and month=06, so it goes across month 12 to 1. Is this tricky for cdo?
Please help.
Cheers Mikko

hi Mikko!
it's hard to say without the whole script and the error.
cheers

It is a one-liner so all code is in there. The bash parameters year and month I gave as well.

And the error message is the title!

I print the command line rathen than executing them because I don't have the data:

So what I see is that '{}' is replaced by the integers upto 50, but '$year${month}' is left untouched. That's why I thought these variables must be set somewhere else. You could add '-v' to the parallel options to see which CDO call fails. then we can debug this call.

sorry - I missed the year/month values from the text

Here is the bias file and one member (6) to test with.
thank you for your support!

cdo --eccodes -ymonadd -selname,2d era5-ecsf_2000-2019_t+sw+sd-monthly-eu-bias.grib -remapbil,era5-eu-grid -selvar,2d ec-sf_202006_all-24h-eu-6.grib o.gribperfectly reproduces your error. the inputs lool ok to me, so I think this is a bug in CDO.

The second input file of ymonadd must contain the monthly mean values. The input streams must therefore be swapped:
cdo --eccodes -ymonadd -remapbil,era5-eu-grid -selvar,2d ec-sf_202006_all-24h-eu-6.grib -selname,2d era5-ecsf_2000-2019_t+sw+sd-monthly-eu-bias.grib o.grib

ah, right. THIS addition is not commutative! 
now it works out-of-the-box
