CHECK_FILE - unable to find time variable in input NetCDF

[vivek]

Dear All,

i am getting following error,

CHECK_FILE - unable to find time variable in input NetCDF file:
/2000-2008/era_airtemp_2000_2008.nc
variable name does not contains the "time" string.

my NetCDF file details are below,

netcdf era_airtemp_2000_2008 {
dimensions:
XI_RHO = 361 ;
ETA_RHO = 253 ;
TAXIS = UNLIMITED ; // (26241 currently)
variables:
double XI_RHO(XI_RHO) ;
XI_RHO:standard_name = "grid_longitude" ;
XI_RHO:units = "degrees" ;
XI_RHO:axis = "X" ;
double ETA_RHO(ETA_RHO) ;
ETA_RHO:standard_name = "grid_latitude" ;
ETA_RHO:units = "degrees" ;
ETA_RHO:axis = "Y" ;
double TAXIS(TAXIS) ;
TAXIS:standard_name = "time" ;
TAXIS:units = "days since 1988-12-31 00:00:00" ;
TAXIS:calendar = "standard" ;
double AIR_TEMP(TAXIS, ETA_RHO, XI_RHO) ;
AIR_TEMP:long_name = "TAIR[GT=TAXIS@ASN]" ;
AIR_TEMP:_FillValue = -1.e+34 ;
AIR_TEMP:missing_value = -1.e+34 ;
AIR_TEMP:history = "From roms_blk_at_2000" ;

// global attributes:
:CDI = "Climate Data Interface version 1.6.2 (http://code.zmaw.de/projects/cdi)" ;
:Conventions = "CF-1.0" ;
:history = "Mon Aug 22 11:17:05 2016: cdo mergetime era_airtemp_2000.nc era_airtemp_2001.nc era_airtemp_2002.nc era_airtemp_2003.nc era_airtemp_2004.nc era_airtemp_2005.nc era_airtemp_2006.nc era_airtemp_2007.nc era_airtemp_2008.nc era_airtemp_2000_2008.nc\n",
"FERRET V6.842 21-Aug-16" ;
:CDO = "Climate Data Operators version 1.6.2 (http://code.zmaw.de/projects/cdo)" ;
}


please help me to how to change "check_multifile.F" progreme according to my data...

You need to change the netcdf file instead. Just add the "time" attribute pointing to "TAXIS" to the AIR_TEMP variable and ROMS should be able to find it:

Code: Select all

ncatted -O -a time,AIR_TEMP,a,c,TAXIS era_airtemp_2000_2008.nc

ncatted comes as part of the nco package from unidata.

I done like that, till i am getting error.

Dear Kate.

I am waiting for your reply. i followed your suggestion, till i am getting error

Well, I don't know why this is happening either. I would compile in debug mode and watch what happens in a debugger. Failing a debugger, I would add print statements in the appropriate place, which is probably get_cycle.F.
