| | 38 | 2 hydrology schemes are implemented in ORCHIDEE. An old 2 bucket scheme called Choisnel and a newer multilayer scheme called CWRR. In _v5 configurations only the 2-bucket Choisnel scheme can be used. In the _v6 configurations or newer offline versions the choice between the two schemes can be done. Choose the hydrology scheme in the following way : |
| | 39 | * in _v5 and _v6 configurations by setting !DefSuffix=CWRR or !DefSuffix=Choi in the section [!UserChoices] in orchidee.card. The variable !DefSuffix will be used to copy the corresponding orchidee.def file from PARAM directory, see the line : |
| 77 | | |
| | 79 | The output levels in ORCHIDEE are controlled by the xml files that have to be present during run time. Following files are needed : iodef.xml, context_orchidee.xml, field_def_orchidee.xml and file_def_orchidee.xml. They are stored in the model directory ORCHIDEE/src_xml and in the configuration directory PARAM/. You can see the copy of these files and where they are stored in the orchidee.card or orchidee_ol.card. file_def_orchidee.xml contains a description of predefined files and their variable content. All variables modified by the configuration are marked with _AUTO_. These variables can be changed directly in the file if you want. Otherwise the values set in config.card and/or comp.card will be used. In config.card the choice of output file and frequency is done using the !WriteFrequency option in section [SRF] and [SBG] : |
| | 80 | * '''[SRF]''' : The first frequency corresponds to the output frequency for the sechiba_history.nc file. The available frequencies are: xY, xM, 5D, 1D and xs, where x is an integer and s means seconds. This file is required. If you add HF, a second sechiba_out_2.nc file will be written with the 3H frequency. |
| | 81 | * '''[SBG]''' : Only one frequency (xY, xM, 5D, 1D or xs) can be specified. The same frequency is applied to both the stomate_history.nc and stomate_ipcc_history.nc files. |

| | 85 | |
| | 86 | The easiest way to personalise the output is to modify directly in PARAM/file_def_orchidee.xml. You can change the variables marked equal _AUTO_ as you wish. In that case you do not need to change in config.card. You can remove or modify the variables as you need which according to the rules for XIOS. |
| | 87 | |
| 81 | | * The !WriteFrequency variable in the [SRF] section induces a change of the WRITE_STEP variable in orchidee.def. WRITE_STEP determines the output frequency for the sechiba_history.nc file. The available frequencies are: xY (x years), xM (x months), 5D(5 days), 1D (1 day), xs (x seconds). This file is mandatory. If you add HF a second sechiba_out_2.nc file will be written with the 3H frequency. |
| 82 | | * The !WriteFrequency variable in the [SBG] section induces a change of the STOMATE_HIST_DT variable in orchidee.def. STOMATE_HIST_DT determines the output frequency for the stomate_history.nc file. The stomate_history_ipcc.nc file always has daily outputs. |
| 83 | | * orchidee.card |
| 84 | | * sechiba_LEVEL : mandatory variable, no default value, it varies between 0 and 11. The SECHIBA_HISTLEVEL variable is set to sechiba_LEVEL. This variable determines the number of variables written in sechiba_history.nc. |
| | 91 | * The !WriteFrequency variable in the [SRF] section induces a change of the WRITE_STEP variable in orchidee.def. WRITE_STEP determines the output frequency for the sechiba_history.nc file. The available frequencies are: xY (x years), xM (x months), 5D(5 days), 1D (1 day), xs (x seconds). This file is mandatory. If you add HF a second sechiba_out_2.nc file will be written with a 3 hour frequency. |
| | 92 | * The !WriteFrequency variable in the [SBG] section induces a change of the STOMATE_HIST_DT variable in orchidee.def. STOMATE_HIST_DT determines the output frequency for the stomate_history.nc file. The stomate_history_ipcc.nc file has always daily output frequency. |
| | 93 | * orchidee.card (or sechiba.card in offline configuration) |
| | 94 | * sechiba_LEVEL : mandatory variable, no default value, it varies between 0 and 11. This value is used in orchidee.def/run.def to set SECHIBA_HISTLEVEL variable. This variable determines the number of variables written in sechiba_history.nc. |
