Cycling in the IFS-ARPEGE-AROME code: a GIT view, April 2019

Patricia — 2019-04-17T07:55:15Z

The diagram prepared by Alexandre Mary illustrates the evolution of cycles in the common code IFS-ARPEGE-AROME in the GIT repository of Meteo-France.
Main features to remember: all the main cycles (e.g. CY43T2, CY46) are tags on the master branch. a T cycle (e.g. CY47T1) is constructed as a merge of several individual branches, having the same starting point, usually a common cycle. the construction of a T cycle is processed in one go; then some so-called phasing corrections are brought in (…)

MITRAILLETTE: ENVIRONNEMENT FILES AND USER'S GUIDE. VERSION v122018.

Karim Yessad — 2018-12-20T00:00:00Z

Abstract:
MITRAILLETTE is a software designed to do some basic validations on ARPEGE, ALADIN, AROME, and versions used by ALADIN or HIRLAM partners. It is shared between METEO-FRANCE, ALADIN partners and HIRLAM partners. It is currently not used by ECMWF.
The current design of MITRAILLETTE allows to use it on different machines with minimal adaptations concentrated in a reduced number of environnement files.
This document explains how to use MITRAILLETTE, and provides information how (…)

Meteo-France's GIT toolbox: GIT-tools

Patricia — 2016-09-07T08:00:00Z

GIT-GCP toolbox for Toulouse SRC, Feb. 2013
This document by Claude Fischer introduces the GIT toolbox, developed at Meteo-France (MF) and used since CY39T1/CY40 as Source Code Repository (SCR) in Toulouse. Therefore, these GIT-tools also become a reference device for Aladin and Hirlam partners committing code to MF's based common libraries.
The note is a shortened translation of the comprehensive GIT-tools documentation written by S. Martinez (COMPAS/GCO of MF). The latter in French, (…)
