Lagrangian analyses of the coupled simulations will be performed by
Sabrina Speich and Bruno Blanke of the LPO.
The MOTIF participants are requested to suply
Sabrina Speich and Bruno Blanke with output fields that fit
ARIANE's formalism, in order to help them derive fast and reliable
Lagrangian diagnostics from the participants' results.
Basically, the models' outputs have to be adjusted to the structure of
a C-grid (introduced in Arakawa's classification [1981]), as it is
their standard grid format as well as a natural framework to express
mass conservation. More details can be found in the MOTIF and the ARIANE format document.
Please get directly in touch with Sabrina Speich and Bruno Blanke to
send the requested monthly ocean fields of a typical/climatological
year gridded or re-gridded on a C-grid.
The special ocean fields will maybe be stored in a special
section of the MOTIF database, eventhough they
are (probably) not on a regular grid. Please try to meet the
IPCC/MOTIF constraints as much as possible. The
best way to do it is probably to write a small program to rewrite your
output fields so that they are as close as possible to what is
described in the Requirements for IPCC Standard Output on the
MOTIF and the IPCC Requirements page.
The names of the files should use the following template:
varname_O_SE_grid_modelorlab_experiment.nc
where grid is the name of the ocean model's grid
(e.g. orcagrid).
