Forcing file names should be in the form of variable.year.nc`. In the namelist you provide a full path to the file and variable. name in the form of:
nm_xwind_file = '/path/to/forcing/CORE2/u_10.'
nm_xwind_file=’’ Name of the file with winds.
nm_ywind_file=’’ Name of the file with winds.
nm_humi_file=’’ Name of the file with humidity.
nm_qsr_file=’’ Name of the file with solar heat.
nm_qlw_file=’’ Name of the file with Long wave.
nm_tair_file=’’ Name of the file with 2m air temperature.
nm_prec_file=’’ Name of the file with total precipitation.
nm_snow_file=’’ Name of the file with snow precipitation.
nm_mslp_file=’’ Name of the file with air pressure at sea level.
nm_xwind_var=’’ Name of the variable in file with wind.
nm_ywind_var=’’ Name of the variable in file with wind.
nm_humi_var=’’ Name of the variable in file with humidity.
nm_qsr_var=’’ Name of the variable in file with solar heat.
nm_qlw_var=’’ Name of the variable in file with Long wave.
nm_tair_var=’’ Name of the variable in file with 2m air temperature.
nm_prec_var=’’ Name of the variable in file with total precipitation.
nm_snow_var=’’ Name of the variable in file with total precipitation.
nm_mslp_var=’’ Name of the variable in file with air pressure at sea level.
nm_nc_iyear=1948 First year of the forcing.
nm_nc_imm=1 Initial month of time axis in netCDF.
nm_nc_idd=1 Initial day of time axis in netCDF.
nm_nc_freq=1 Data points per day (i.e. 86400 if the time axis is in seconds)
nm_nc_tmid=1 It’s 1 if the time stamps are given at the mid points of the netcdf file, 0 otherwise (i.e. 1 in CORE1, CORE2; 0 in JRA55).
The following options control if the forcing files for particular variables are used or not.
l_xwind=.true.

l_snow=.true.
nm_runoff_file=’’ Name of the runoff file.
runoff_data_source =’CORE2’ Other options are
Dai09,CORE2nm_sss_data_file=’’ Name of the sea surface salinity restoring data file.
