Introduction.
With the help of our HIRLAM partners, a portable version of MITRAILLETTE has been implemented in 2008,
after a former version of MITRAILLETTE: it is designed to do a list of validations for LAM models. Additionally,
a portable version of MITRARP has been implemented in February 2009, designed for ARPEGE validations; its
design is identical to the one of MITRAILLETTE. During the first term of 2014, both environments have been
merged into one, so MITRAILLETTE can be now used for both global model and LAM model validations.
The current design of MITRAILLETTE allows to use it on different machines with minimal adaptations
concentrated in a reduced number of environment files: that allows a minimal amount of work when scripts
must be adapted to a new machine.
This document explains how to use MITRAILLETTE, and gives an extensive list of validated configurations.
Use of the following procedures assumes that the following variables are defined in .bash profile of the machine
where validation is done:
export
export
export
export
STATION=[name of the machine]
SHOME=${HOME}/SAVE
PMAHOME=/home/gmap/mrpm/marguina
REKHOME=/home/gmap/mrpm/khatib
Modifications since the last version:
• Distributed memory validations:
– only one combination for A and B level distribution is validated.
– NPRGPEW, NPRGPNS, NPRTRW, NPRTRV has been removed from namelists, and is
automatically computed in SUMPINI.
• The following configurations have been removed for global model: 8HEX, 8HLX, MHES, MHLS, FILC,
FILD, FPMA.
• The following configurations have been removed for LAM model: AH8E, AH8T, AC5T, AC4T.
• AR1T with LGWADV=T now runs with RDAMPPD=20., ND4SYS=2; add one case “pccios” to use io
server.
• More generally, all NH runs match RDAMPPD=RDAMPT.
• ANLY and MNLY: cases DD4SL2C15F and DD4SL2C15E have been replaced by DD4SL2C45F and
DD4SL2C45E
• ANLY and MNLY: case DD4SL2C15F has been replaced by DD4SL2C45F; case DD4SL2C15E has been
removed.
• FPLB and FILB: now run with LGWADV=T, ND4SYS=2.
• AN1T: case ”pcc” now runs with ND4SYS=2.
• AN2T: case ”gwadv” now runs with ND4SYS=2.
• AC1U: now runs with ND4SYS=2.
• New configuration MHLI (= MHLJ with io server).
• For SURFEX, use only FA files.

File environment and user’s guide for MITRAILLETTE.
∗ List of files: On the machine where validation is done, a directory ${HOME}/mitraille must be created.
Under this directory one must find the following files and call tree (example is given for CY41T1 validation):
cy41t1 (dir)
mitra_home_location
mitraillette_v122014.x
namelist/cy41t1/nam...
PRO_FILE.cy41t1_arpmonoref
