Unsupported TIMEUNIT

Added by Parisa Khorsand 7 months ago

I have a netcdf file that I want to mask ocean areas. However, when I type the cdo sinfon command, it gives me the Unsupported TIMEUNIT error. I will send you the error file and the cdo version.

best regards

Parisa

Hi Parisa,

as the CDO warning is telling you the time units format is wrong. You can see the time values with

ncdump -v Time surface_d02_20130109.nc

Output:

 Time = 2013011000, 2013011001, 2013011002, 2013011003, 2013011004, 
    2013011005, 2013011006, 2013011007, 2013011008, 2013011009, 2013011010, 
    2013011011, 2013011012, 2013011013, 2013011014, 2013011015, 2013011016, 
    2013011017, 2013011018, 2013011019, 2013011020, 2013011021, 2013011022, 
    2013011023, 2013011100, 2013011101, 2013011102, 2013011103, 2013011104, 
    2013011105, 2013011106, 2013011107, 2013011108, 2013011109, 2013011110, 
    2013011111, 2013011112, 2013011113, 2013011114, 2013011115, 2013011116, 
    2013011117, 2013011118, 2013011119, 2013011120, 2013011121, 2013011122, 
    2013011123 ;

Now, you can fix the time with CDO:

cdo -r -setreftime,2013-01-01,00:00,1hour -settaxis,2013-01-10,00:00,1hour surface_d02_20130109.nc surface_d02_20130109_correct_time_units.nc
