Sphere to sphere transforms in spectral space in the cycle 39 of ARPEGE/IFS: configuration 911 (November 2012)

Karim Yessad — 2012-11-27T23:00:00Z

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 (...) - Configurations

Configuration 801 in the cycle 39 of ARPEGE/IFS (November 2012)

Karim Yessad — 2012-11-27T23:00:00Z

Abstract: This documentation describes the algorithmic and technical aspects of the configuration 801 of ARPEGE/IFS, which allows in particular to do sensitivity studies. An example of namelist is provided. This configuration is used to do sensitivity studies and can help to answer the two following questions : defining a scalar cost function, what is the sensitivity of this cost function to some basic meteorological variables ? one does an "experiment forecast" and uses a "reference (...) - Configurations

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

Patrick SAEZ — 2008-02-05T09:21:17Z

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. Contents : I. Introduction II. Enchainement des tâches III. Détail des étapes IV. Base MARS et requêtes V. Scripts a (...) - Configurations

Configuration 951 in the cycle 31t1 of ARPEGE/IFS (2006)

Karim Yessad — 2006-08-22T13:58:00Z

Abstract: This documentation describes the configuration 951 of ARPEGE/IFS. This is an obsolescent configuration which reads a field in two files (reference and experiment versions) and compares the two versions. Contents: Introduction. Action of configuration 951. Organigramme. List of useful variables. References and internal notes. - Configurations

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

2000-03-01T07:54:00Z

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.
