Integrating COREII forcing in nemo tags v3.2 / libigcm tags v1.4

Purposes:

• Document the using of COREII forcing for NEMO (tag v32, revision : 1803), in configuration ORCA2_LIM, with libIGCM (tags v1.4, revision : 200).

• ​Documentation of CORE :

Step by step:

Preparing COREII forcing files on ORCA2 grid

climatological files

1. Download COREII forcing files : ​CYNF
   
2. Interpolation of forcing files (with cdo (version 1.4.0.1) & nco (version 3.9.5) ) : ​example of script
3. create coefr weights for runoffs ( NOTE: in our case we created weights = 0, because max of runoff in COREII is < 50 Sv ) File runoff with 2 weight's coefficient (coefr0 is 0 averywhere, and coefr ......): https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/runoff_core_monthly.nc runoff_core_monthly.nc

NOTE: you can find interpolated files at ​IDRIS

4. removed part "if ORCA2" in sbcrnf.F90
5. preparing script ".pro" for post processing with idl https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/std_plots.pro.clima example for plots, and https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/std_ts.pro.clima example for time series
6. automatize creation of pdf or html, by shell script https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/std_plots.sh.clima example for plots , and https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/time_series.sh.clima example for time series

and all detailed scripts for single : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/plots.tar.gz plots and for single : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/ts.tar.gz time series

NOTE : it is better to do not give name with "_" because to have timeseries the script looks for experience name and dates in filenames, and to split filename it uses "_" like separator.

Plots (Climatology)

Job characteristics :

 forcing : COREII 
 2000 years of simulation
 strategy of output: 
         writing frequency of output : 10 years
         ocean output : all years annual mean output (T, U, V)
         ocean output : true monthly output for the following decades : 1-10, 41-50, 91-100, 491-500, 991-1000, 1491-1500, 1991-2000
         oce restart : 1 year every ten years 
         ice output : 1 month for all years 
         ice restart : 1 year every ten years 
         restart of the system saved each ten years

Inter Annual files

NOTE: runoff for interannual is the same of climatological so be careful to change (if necessary) the name in opa9.card!!!!

1. Download COREII forcing files : ​CIAF
   
2. For Inter Annual case you can download "Combined years data sets" from 1948 to 2007 (60 years). Here there is a script to extract every year from global file : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/script_extract.sh example of extract script
3. Interpolation of forcing files (with cdo (version 1.4.0.1) & nco (version 3.9.5) ) : ​example of script
   

In this case I needed also a script to move "_year" at the end of file to work with Inter Annual forcing files, because in namelist you have to put your file name and NEMO add the year at the end of the file name

There are 2 cases:
3.1 If this script of example is used you remove part with date (04MAR2010)
3.2 Or you can leave part with date of file's creation

Here you have corresponding examples of script to move "_year" in filename :
3.1 https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/change_names.DDMMMYYYY.sh change_names.DDMMMYYYY.sh
3.2 https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/core2_cmip/change_names.date.sh change_names.date.sh

NOTE: you can find interpolated files at
​http://dodsp.idris.fr/reee605/CORE2_interan/ IDRIS

4. removed part "if ORCA2" in sbcrnf.F90
5. in fldread.F90 changed: "IF( llprev .AND. sdjf%num == 0 ) " in "IF( llprev .AND. sdjf%num <= 0 )"
6. added in subbasins_orca21.nc mask for indopacific ocean and indian ocean without red sea.
7. preparing script ".pro" for post processing with idl (same as climatological case)
8. automatize creation of pdf or html, by shell script (same as climatological case)
