BATOR’s Changes and input files used (Observations)
Friday 7 July 2017
by
1/ Since CY42 some changes have been made in BATOR :
- ’ficdate’ file which describe timeslots is deprecated.
- ’refdata’ files are replaced by ’batormap’ ones
2/ How to write a param_bator.cfg input file (from CY43)
3/ soon ! (on writing) : namelist for Bator
Getting observational data from BDMO for atmospheric models (Observations)
Friday 7 July 2017

Vous retrouverez ici :
- la documentation concernant les outils d’extractions (pour les donnees au format BUFR, NETCDF ou HDF5) utilises pour les modeles atmospheriques,
- une documentation sur un outil d’extraction de donnees (incluse dans la doc citee ci-dessus), disponible sur ce site ou sur Hendrix.

Tools for BUFR files, Oulan, (BDMO) Data extract (Observations)
Friday 7 July 2017

Here you will find here some usefull tools to deal with BUFR files. You may use them ’out of the box’ on your GMAP’s workstation. Program Oulan, and tools to extract observational data from BDMO are also available.
CFU (cumulated fluxes) and XFU (instantaneous fluxes) in the cycle 45 of ARPEGE/IFS. (Diagnostics)
Thursday 29 June 2017
by
Table of contents Abstract RESUME Contents
This documentation describes some diagnostics done on the physical fluxes: CFU (cumulated fluxes) and XFU (instantaneous fluxes). Some algorithmic aspects and technical aspects (organigramme for example) are (...)
Digital filtering initialisation in the cycle 45 of ARPEGE/IFS. (Dynamics)
Thursday 29 June 2017
by
Table of contents Abstract RESUME Contents
This documentation describes the digital filtering initialisation (DFI) and its implementation in ARPEGE/IFS. Some theoretical aspects are recalled. The way of implementing the DFI in ARPEGE/IFS is then described, (...)
Semi-Implicit spectral computations and predictor-corrector schemes in the cycle 45 of ARPEGE/IFS. (Dynamics)
Thursday 29 June 2017
by
Table of contents Abstract RESUME Contents
This documentation describes two types of schemes allowing to stabilize the numerical discretizations of the models: the semi-implicit scheme and the iterative centred-implicit scheme (sometimes called (...)
Semi-Lagrangian computations in the cycle 45 of ARPEGE/IFS. (Dynamics)
Thursday 29 June 2017
by
Table of contents Abstract RESUME Contents
The general purpose of this documentation is to describe the set of equations used, and also the way to integrate the dynamics of the model with the semi-Lagrangian method currently implemented in ARPEGE/IFS. The (...)
Integration of the model equations, and eulerian dynamics, in the cycle 45 of ARPEGE/IFS. (Dynamics)
Thursday 29 June 2017
by
Table of contents Abstract RESUME Contents Appendices
This documentation can be seen as a long introduction to modeling. The general purpose of this documentation is to describe the set of equations used, and also the way to integrate the dynamics of the (...)
Horizontal diffusion computations in cycle 45 of ARPEGE/IFS. (Dynamics)
Thursday 29 June 2017
by
Table of contents Abstract RESUME Contents
This documentation recalls some basics about horizontal diffusion schemes, and describes how they are implemented in ARPEGE/IFS and its LAM (limited area model) counterpart. The ECMWF way of implementing them (which (...)
Spectral transforms in the cycle 45 of ARPEGE/IFS. (Dynamics)
Thursday 29 June 2017
by
Table of contents Abstract RESUME Contents Appendices
ARPEGE/IFS and ALADIN are spectral models, so this documentation has for purpose to describe the spectral transforms done. The present note has for aim to give a brief summary of the spectral method (how (...)
