error "Numeric conversion not representable"
Added by Ufuk Utku Turuncoglu over 13 years ago
Hi,
I try to calculate monthly mean using following command,
cdo monmean runoff_x.nc tmp.nc
but CDO gives,
cdf_put_vara_double : ncid = 131072 varid = 3 val0 = 0.005725
Error (cdf_put_vara_double) : NetCDF: Numeric conversion not representable
error. The data is not packed and variables are in float data type. I also try to add "-b 32" option but result is same. "-b 64" is working but in this case data size is increasing. Any suggestion?
PS: CDO version 1.5.0

Hi Ufuk,
We have no idea how this could happen.
Could you please attach your netCDF file.
Cheers, Uwe

Hi,
Sorry for late response. You can find the file as attachment. The original data is huge so i just only include a month. The following command causes error,
cdo monmean runoff_test.nc runoff_test_mon.nc
Warning (scanVarAttributes) : NetCDF: Variable not found - rcm_map

cdf_put_vara_double : ncid = 131072 varid = 4 val0 = 0.003013

The runoff data has missing values which are filled with _FillValue = -1.e+34f. Furthermore there are some time steps with a few values in the range -1e-38 and -1e33 and some values with "-inf". The "-inf" values causes the problem. Solution for this problem is to change the "-inf" values also to missing values:
cdo monmean -setctomiss,-inf runoff_test.nc runoff_test_mon.nc
Best regards,
Uwe
