Change Surface Boundary Conditions
How to change Surface Boundary forcing files
By default from nemo web site :
http://www.nemo-ocean.eu/index.php//Using-NEMO/Configurations/ORCA2_LIM
you have forcing files for bulk CLIO formulae
If you want to use other atmospheric forcing methods you can chose :
analytical
flux
bulk ( CLIO formulae )
bulk ( CORE formulae )
coupled
Example : using CORE bulk formulae
- in modipsl/config/ORCA2_LIM/IGCM00/COMP/opa9.card you have to :
- decomment OPA_version if you want to use COMMON ACCOUNT
( https://forge.ipsl.jussieu.fr/nemo/wiki/private/libIGCM/common_account )
- choose if you want to do an
interannul run ( Interannual_Run=y )
climatological run ( Interannual_Run=n )
- List Surface Boundary Condition original files name ( get by the job )
List_jobsbc=(radlw_DFS4-ORCA2, radsw_DFS4-ORCA2, q2_DFS4-ORCA2, t2_DFS4-ORCA2, u10_DFS4-ORCA2, v10_DFS4-ORCA2, snow_DFS4-ORCA2, precip_DFS4-ORCA2)
NOTA BENE : It is very important to control variable name in netcdf files. In namelist you have to put same variable name that you have in netcdf files.
- List Surface Boundary Condition files name expected by NEMO ( same as the ones in namelist )
List_runsbc=(qlw_core, qsw_core, q2_core, t2_core, u10_core, v10_core, snow_core, precip_core)
(NOTA BENE : you can leave List_runsbc=(), and this means that List_runsbc=List_jobsbc=(radlw_DFS4-ORCA2, radsw_DFS4-ORCA2, q2_DFS4-ORCA2, t2_DFS4-ORCA2, u10_DFS4-ORCA2, v10_DFS4-ORCA2, snow_DFS4-ORCA2, precip_DFS4-ORCA2) )
- in modipsl/config/ORCA2_LIM/IGCM00/PARAM/namelist :
- activation of bulk core formulae in Surface Boundary Condition function ( namsbc )
ln_blk_core = .true.
- set correct frequency, name and interpolation in CORE bulk formulae ( namsbc_core )
file name frequency (hours) (if <0 months) variable name time interpol. (logical) clim (T/F) 'yearly' or monthly weights filename rotation pairing sn_wndi 'u10_core' 6. 'u10' .true. .false. 'yearly' ' ' ' ' sn_wndj 'v10_core' 6. 'v10' .true. .false. 'yearly' ' ' ' ' sn_qsr 'qsw_core' 6. 'radsw' .true. .false. 'yearly' ' ' ' ' sn_qlw 'qlw_core' 6. 'radlw' .true. .false. 'yearly' ' ' ' ' sn_tair 't2_core' 6. ' t2' .true. .false. 'yearly' ' ' ' ' sn_humi 'q2_core' 6. 'q2' .true. .false. 'yearly' ' ' ' ' sn_prec 'precip_core' -1. 'precip' .true. .false. 'monthly' ' ' ' ' sn_snow 'snow_core' -1. 'snow' .true. .false. 'monthly' ' ' ' '
!
cn_dir = './' ! root directory for the location of the bulk files
ln_2m = .true. ! air temperature and humidity referenced at 2m (T) instead 10m (F)
alpha_precip= 1. ! multiplicative factor for precipitation (total & snow)
