Report of activity between 15/12/2008 and 15/05/2009

Technical points

Tested till :

• NEMO trunk version revision 1407
  
• libIGCM trunk version revision 110
  
• with calendar type : 360d, noleap.

( I'm waiting for a tag of libIGCM )

Modifications at the code :

1. "Dynamic monitoring"

We can say dynamic monitoring monitoring of variables choosen by user (see : https://forge.ipsl.jussieu.fr/nemo/wiki/private/libIGCM/postprocessingpage#HowtoactivatedynamicMonitoring25022009 )

changed files :

monitoring01_opa9_ORCA2.cfg
monitoring01_lim2_ORCA2.cfg
monitoring.job

and

opa9.card
lim2.card

( NOTA : tested with libiGCM tag version libIGCM_v1_2, revision 50.

now monitoring is changed a lot, I tested almost all but when there is a new tag I'll do another test)

2. "common accounts"

To store boundary conditions and forcing files we can use common account of ipsl ( see : https://forge.ipsl.jussieu.fr/nemo/wiki/private/libIGCM/common_account#Usingcommonaccounttostoreboundaryconditions )

changed files :

add ~comptecommun/dmf/IGCM/BC/OCE/

all configurations : ORCA2_LIM2
ORCA2_LIM2_PISCES
IPSLCM5
IPSLCM4_v1
IPSLCM4_v1_OASIS3
IPSLCM4_v2
IPSL_ESM_V1

and ORCA2_LIM2/v3
and ORCA2_LIM2/v3_1

to separate different boundary conditions, linked to NEMO version ( versions differ only for bathymetry now )

added:

~commonaccount/dmf/IGCM/STORAGE/BC/OCE/NEMO/ORCA2_TEST/

waiting for arnaud caubel test ( then it will be named only ORCA2 )

3. "new cards"

To use common accounts and to be coherent with old version of opa we changed nemo.cards in opa9.cards

changed files :

opa9.card
opa9.driver
in config.card "Tag_Name"

4. "like coupled"

After a meeting of engenieers and researcher to point out direction for IPCC we decided that "NEMO forced" has to have same output data, monitoring and atlas of coupled. So I add same variables of coupled used in monitoring and in ZNL atlas. ( NOTA : also because if I want to use monitoring by default; monitoring01... (CONTROLLARE!!!!!!!!)

I can't, because in monitoring.job there is an "exit if timeseries does not exists", so I'm obliged to have same timeseries if I want to use monitoring!)

5. "new diaptr"

changed mpi version, was no good with atlas

6. "interannual"

working in progress

7. "monitoring comparison"

is no still ok!

8. "monitoring & atlas"

decide if we have to customize it for a more "readable" version

Open points

• we have to point out interannual runs :

what works : opa can find surface boundary conditions' files for december of previous year in jannuary of current year, and for jannuary of next year in december of current year. This is means that opa can do a correct interpolation.

what does not work : at firts timestep opa is stopped because abs(U) is greather then 20 we have still to understand why

• to test with calendar type : leap ( not having priority now )
