LMDZ XIOS outputs

You can control many outputs using XIOS (see XIOS_output_controls for details).

If you add fields using the write_output() routine (for example in physiq_mod), you will need to add a corresponding field in field_def_physics.xml. For example,

         call write_output("temperature","temperature","K",zt)

corresponds to

            <field id="temperature"
                   long_name="Atmospheric temperature"
                   unit="K" />
            

You can automatize the translation fortran->XML via the script UTIL/convert_diagfi_to_xml.py (by pasting the write_output() lines into the fortran_input file read by the script).

You will need to know if the variable is 1D,2D or 3D before putting it in the right section of the field_def_physics.xml file though.

Parameter files

iodef.xml
context_pcm_physics.xml
field_def_physics.xml
file_def_physics.xml

XML example files for XIOS can be found in LMDZ.GENERIC/deftank/xios for the generic PCM.

XML example files are different for DYNAMICO. See Controling outputs in the dynamics with DYNAMICO. You will find under deftank/dynamico example files for DYNAMICO with generic physics.

file_def_physics.xml

This file (example here) lists the output files you need, and which variables to write in it.

Output files

The main output file, equivalent to diagfi.nc is Xhistins.nc. This file is controlled mainly by file_def_physics.xml
