Integrating COREII forcing in nemo v3.2 / libigcm


Purposes:


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



Step by step:

Preparing COREII forcing files on ORCA2 grid

TO DO :

understand how to sort rain without key_coupled (can we change iodef.xml file?)

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/private/core2_cmip/runoff_core_monthly.nc runoff_core_monthly.nc

NOTE: for the moment you can find interpolated files at IDRIS and CCRT

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

Configuration of libIGCM files:

  1. COMP/opa9.card : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/private/core2_cmip/opa9.card opa9.card
  2. COMP/opa9.driver : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/private/core2_cmip/opa9.driver opa9.driver
  3. PARAM/namelist : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/private/core2_cmip/namelist namelist
  4. PARAM/iodef.xml : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/private/core2_cmip/iodef.xml iodef.xml
  5. config.card : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/private/core2_cmip/config.card config.card

Plots (Climatology)

Job characteristics :

 forcing : COREII 
 2000 years of simulation
 output: annual mean (T,U,V)
         monthly mean (ice)
         monthly mean (T,U,V) for year 50, 100, 500, 1000, 1500, 2000
 (used ipcc's names, see table above)

https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/private/core2_cmip/clima_ts.pdf timeseries.pdf


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/private/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/private/core2_cmip/change_names.DDMMMYYYY.sh change_names.DDMMMYYYY.sh
3.2 https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/private/core2_cmip/change_names.date.sh change_names.date.sh

NOTE: for the moment you can find interpolated files at
u/rech/eee/reee605/CORE2_interan_lastvers/OCE/ORCA2_LIM2 IDRIS (version 04MARS2010)
dmnfs13/cont003/flavoni/CORE2_interan_lastvers/OCE/ORCA2_LIM2 CCRT (version 04MARS2010)

( note: it is also available previous version :
u/rech/eee/reee605/CORE2_interan/OCE/ORCA2_LIM2 IDRIS: version 26JAN2010
dmnfs13/cont003/flavoni/CORE2_interan/OCE/ORCA2_LIM2 CCRT: version 26JAN2010

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

Configuration of libIGCM files:

  1. COMP/opa9.card : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/private/core2_cmip/opa9_inter.card opa9.card
