Printing CDO results to the terminal?
Added by Walter Hannah about 9 years ago
I'd really like to have a set of commands to quickly check some basic things about some climate model output. The most basic thing is to print the monthly or yearly global averages of surface temperature from a series of netcdf files.
I realize I can't just do:
cdo yearmean output.*.nc
because it wants an output file.
I also tried using something like this:
cdo infon -fldmean -selvar,TS output.*.nc
And this works for a single file, but for multiple files it just spits out the spatial average for every time.
I also tried messing around with the "output" cdo command, but so far this hasn't worked either.
Does anyone have a good way to achieve this?
Thanks,
Walter Hannah

Try wildcards with quotation:
cdo -s -infov -fldmean -yearmean -select,name=water_u 'year_201*'
This prints
ram@luthien:~/local/data/cdo cdo -s infov -fldmean -yearmean -select,name=water_u 'year_201*' [10:12:59|15-09-08]
-1 : Date Time Level Gridsize Miss : Minimum Mean Maximum : Parameter name
1 : 2013-05-01 00:00:00 0 1 0 : -0.026452 : water_u
2 : 2014-05-01 00:00:00 0 1 0 : -0.026955 : water_u
For minimal output, you could use the outputkey operator
ram@luthien:~/local/data/cdo cdo -s outputkey,date,time,value -fldmean -yearmean -select,name=water_u 'year_201*' [10:14:57|15-09-08] # date time value 2013-05-01 00:00:00 -0.0264521 2014-05-01 00:00:00 -0.0269546
input files look like this:
ram@luthien:~/local/data/cdo cdo sinfov year_201* [10:13:03|15-09-08]
