Basics about ARPEGE/IFS, ALADIN and AROME in the cycle 46t1r1 of ARPEGE/IFS.

Karim Yessad — 2019-02-12T00:00:00Z

Abstract:
This documentation has the aim to give a general overview of the ARPEGE/IFS, ALADIN and AROME models, for beginners or for someone which knows some specific points but has no general overview of the whole models. It can be seen as a synthetic sum-up of some other documentations, and it contains also a list of references as complete as possible which form the set of documentations. RESUME:
CETTE DOCUMENTATION A POUR BUT DE DONNER UN APERCU GENERAL DE CE QUE SONT LES MODELES (…)

Sphere to sphere transforms in spectral space in the cycle 46t1r1 of ARPEGE/IFS: configuration 911.

Karim Yessad — 2019-02-12T00:00:00Z

Abstract:
This documentation describes configuration formerly numbered 911 which performs dilatation/contraction matrices: these matrices allow to do spectral transformation between a stretched spectral space and between its unstretched counterpart. Some algorithmic aspects and technical aspects are described. Some namelists are provided to use the configuration 911, which is now externalised in the project UTILITIES. Such transformations can be used in spherical geometry only, and for (…)

Notice d'utilisation de la configuration 901 ISBA (2008)

Patrick SAEZ — 2008-02-05T10:21:17Z

This document (in French) written by Patrick Saez in March 2003 (updated in Feb. 2008) explains how running a 901 configuration. This configuration aims to transform CEP file (GRIB MARS) into ARPEGE files (FA). It is not only a change of format (ex ISBA); after creating ARPEGE files and climatology, a c923 and a c927 will be also necessary to obtain the final files.

ARPEGE/ALADIN : the galaxy (data flow around ARPEGE/ALADIN, 2000)

2000-03-01T08:54:00Z

This document is a slide presentation (including notes) from Ryad El Khatib.
It presents the data flow around ARPEGE/ALADIN software and the multifunctionality of this software :
– ARPEGE/ALADIN : how does it work ?
– What is the namelists file?
– What are the input data ?
– How to make a tidal waves file?
– How to make a historical file Arpege ?
– How to make ALADIN files ?
– The configuration 901
– O.I. Analysis "CANARI" : the configuration 701
– Changing the geometry : the (…)
