Description

Arnaud Caubel noticed using the AR5 version of ORCHIDEE in IPSLCM5A, that the output variable ALLOW_INITPHENO in stomate_history.nc is not reproductible.

This has to be clarified. Verification in the trunk version of ORCHIDEE must be done.

  • Resolution set to fixed
  • Status changed from new to closed

The error has been reproduced with tag 1.9.5 of Orchidee in LMDZOR_v5 configuration at curie. Using the trunk rev 1308 of Orchidee the problem has not been seen. I suppose therefore the problem has been resolved in the source code.

Following tests have been done at curie with LMDZOR_v5 configuration :

* With Orchidee 1.9.5 : 5 simulations with the same set-up and same executable have been done. They are reproductible except for the variable ALLOW_INITPHENO in stomate_history.nc file. All other history files and all restart files are identic. Among these 5 simulations, the first and the fifth are identic. And the second, third and fourth are identic. This means that ALLOW_INITPHENO have 2 different patterns among 5 simulations. These simulations have a lenght of 3 months.

  • With Orchidee trunk revision 1307 : 6 simulations have been done. They are all identic, including all history and restart files. The same set-up as above was used. These simulations have a lenght of 2 years.

All simulations use adjust=n in LMDZ.
