CDO

hi Bianca!

your input files have different variables. you can check it with this for loop:

for file in gfs.*nc; do cdo -s showname $file; done

Thanks for the help Ralf. And would this have the same effect as merging it by time? As the data is forecasted at 6h intervals.

'cat' is just 'concatenation' and since your files are already ordered by data+time (encoded in the filename) 'cat' should work.

you might give it a try and check the result ;-)

Hi Ralf,

Just tried using cat and I get the same error as I did using mergetime. Don

Because some of your files STILL have the same additional variable 'DZDT_P0_L100_GLL0'. try this:

cdo -cat -apply,delname,DZDT_P0_L100_GLL0 [ gfs.0p25.201906*nc ] _all6.nc
cdo -cat gfs.0p25.201905*nc _all5.nc
cdo cat _all5.nc _all6.nc gfs.all.nc

Just tried the above and kept getting segmentation fault:11

At first didn't think it was an issue but when I tried to do your final command it stated that the _all5.nc file did not exist.

do you use the latest CDO release?

I am using v 1.9.8 which I think is the latest.

yes, it is. can you post the commands with the corresponding error?

Sure,

The code I inputted into my terminal was as follows:

cdo -cat -apply,delname, DZDT_P0_L100_GLL0 [/Volumes/WRIGHT/gfs/gfs.0p25.2019052000-2019061418.f048.grib2.wright439424.nc/gfs*.nc] _all5.nc


white-space is crucial here - try this please:

cdo -cat -apply,delname,DZDT_P0_L100_GLL0 [ /Volumes/WRIGHT/gfs/gfs.0p25.2019052000-2019061418.f048.grib2.wright439424.nc/gfs*.nc ] _all5.nc

Thank you so much Ralph for all your help. Will keep all these tips you gave in mind.

It's all been resolved now.

perfect

best wishes
