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
- 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 )
- Choose forcing method ( like in the following examples )
Example : using CORE bulk formulae
- In modipsl/config/ORCA2_LIM/IGCM00/COMP/opa9.card you have to :
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 : If you leave List_runsbc=() 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) and in this case it CAN'T run because these are not same names that in the namelist!
- 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' ' ' ' '
Example : using CLIO bulk formulae
- in modipsl/config/ORCA2_LIM/IGCM00/COMP/opa9.card you have to :
List Surface Boundary Condition original files name ( get by the job )
List_jobsbc=(flx, taux_1m, tauy_1m)
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=(flx, taux_1m, tauy_1m)
NOTA BENE : you can leave List_runsbc=(), and this means that List_runsbc=List_jobsbc=(flx, taux_1m, tauy_1m) and in this case it is ok.
- in modipsl/config/ORCA2_LIM/IGCM00/PARAM/namelist :
- activation of bulk clio formulae in Surface Boundary Condition function ( namsbc )
ln_blk_clio = .true.
- set correct frequency, name and interpolation in CLIO bulk formulae ( namsbc_clio )
file name frequency (hours) (if <0 months) variable name time interpol. (logical) clim (T/F) 'yearly' or monthly weights filename rotation pairing sn_utau 'taux_1m' -1 'sozotaux' .false. .true. 'yearly' ' ' ' ' sn_vtau 'tauy_1m' -1 'sozotauy' .false. .true. 'yearly' ' ' ' ' sn_wndm 'flx' -1 'socliowi' .false. .true. 'yearly' ' ' ' ' sn_tair 'flx' -1 'socliot2' .false. .true. 'yearly' ' ' ' ' sn_humi 'flx' -1 'socliohu' .false. .true. 'yearly' ' ' ' ' sn_ccov 'flx' -1 'socliocl' .false. .true. 'yearly' ' ' ' ' sn_prec 'flx' -1 'socliopl' .false. .true. 'yearly' ' ' ' '
