ncks -O -x -v time_bounds Season_ET.nc Season_ET.nc
The ncks syntax is
ncks [options] input_file.nc [output_file.nc]
where values inside [ ] are optional
In your case, you need to specify the output file different from the input
file
From your case, I did, to generate the netCDF file from CDL
ncgen -o my_in_file.nc my_in_file.cdl
to see the file in ncks
ncks -m my_in_file.nc
to geneare a new file without the 'ET' variable
ncks -v ET -x my_in_file.nc my_out_file.nc
to see the new file
ncks -m my_out_file.nc

Subject: [netcdfgroup] Problem in deleting variables with ncks
Hi,
For some reason, I am not able to delete a variable with ncks (with -x -v
option). Wondering why.....
I am typing
ncks -O -x -v time_bounds Season_ET.nc Season_ET.nc
My netcdf (Season_ET.nc) looks like -
netcdf Season_ET {
dimensions:
time = UNLIMITED ; // (112 currently)
lat = 76 ;
lon = 120 ;
hist_interval = 2 ;
variables:
float ET(time, lat, lon) ;
ET:_FillValue = 1.e+36f ;
ET:cell_methods = "time: mean" ;
ET:long_name = "ET" ;
ET:missing_value = 1.e+36f ;
ET:units = "mm/s" ;
float lat(lat) ;
lat:long_name = "coordinate latitude" ;
lat:units = "degrees_north" ;
float lon(lon) ;
lon:long_name = "coordinate longitude" ;
lon:units = "degrees_east" ;
float time(time) ;
time:long_name = "time" ;
time:units = "days since 1980-10-01 00:00:00" ;
time:calendar = "noleap" ;
time:bounds = "time_bounds" ;
double time_bounds(time, hist_interval) ;
time_bounds:long_name = "history time interval endpoints"
;
// global attributes:
:title = "CLM History file information" ;
:comment = "NOTE: None of the variables are weighted by
land fraction!" ;
:Conventions = "CF-1.0" ;
:source = "Community Land Model CLM4.0" ;
:hostname = "saudi" ;
:username = "mizukami" ;
:version = "cesm1_0_3" ;
:revision_id = "$Id: histFileMod.F90 28831 2011-06-07
06:14:20Z erik $" ;
:case_title = "UNSET" ;
:case_id = "MAURER12K_PN" ;
:Surface_dataset = "surfdata_PN12K.nc" ;
:Initial_conditions_dataset =
"MAURER12K_PN_TEST.clm2.r.spin.nc" ;
:PFT_physiological_constants_dataset =
"pft-physiology.c110425.nc" ;
:RTM_input_dataset = "rdirc_0.5x0.5_simyr2000_c101124.nc"
;

:NCO = "20131105" ;
