[ncl-talk] To split nc file based on timestamp

[Tripura Yerrapothu]

Hello Team,

I am currently looking the command that helps me to split the .nc file
based on time stamp. Below is the file opened using ncdump

netcdf rtma_20190501_T_interp_test {
dimensions:
    time = UNLIMITED ; // (5 currently)
    lon = 309 ;
    lat = 195 ;
variables:
    double time(time) ;
        time:standard_name = "time" ;
        time:long_name = "verification time generated by wgrib2 function
verftime()" ;
        time:units = "seconds since 1970-01-01 00:00:00.0 0:00" ;
        time:calendar = "standard" ;
        time:axis = "T" ;
    float lon(lon) ;
        lon:standard_name = "longitude" ;
        lon:long_name = "longitude" ;
        lon:units = "degrees_east" ;
        lon:axis = "X" ;
    float lat(lat) ;
        lat:standard_name = "latitude" ;
        lat:long_name = "latitude" ;
        lat:units = "degrees_north" ;
        lat:axis = "Y" ;
    float TMP_2maboveground(time, lat, lon) ;
        TMP_2maboveground:long_name = "Temperature" ;
        TMP_2maboveground:units = "K" ;
        TMP_2maboveground:_FillValue = 9.999e+20f ;
        TMP_2maboveground:missing_value = 9.999e+20f ;
        TMP_2maboveground:short_name = "TMP_2maboveground" ;
        TMP_2maboveground:level = "2 m above ground" ;

// global attributes:
        :CDI = "Climate Data Interface version 1.9.3 (
http://mpimet.mpg.de/cdi)" ;
        :Conventions = "CF-1.0" ;
        :history = "Thu Jun 20 15:36:01 2019: cdo intntime,4
rtma_20190501_T_test.nc rtma_20190501_T_interp_test.nc\n",
            "Thu Jun 20 15:31:22 2019: ncrcat

rtma_20190501_T_test.nc\n",
            "Mon Jun 10 16:53:02 2019: cdo

tmp.nc
/home/tripura/2019CMA/Concorde-final/download/201905/20190501/rtma_2019050123_T_MS.nc"
;
        :History = "created by wgrib2" ;
        :GRIB2_grid_template = 30 ;
        :NCO = "4.7.2" ;
        :nco_openmp_thread_number = 1 ;
        :CDO = "Climate Data Operators version 1.9.3 (
http://mpimet.mpg.de/cdo)" ;
}


Now i want this file to split into 5 files i.e.. i am looking for the
command to split the files based on the timestamps.

Please kindly help me on this.

Thank you in advance.
