BATOR’s Changes and input files used (Observations)

Tuesday 26 June 2018 by Frank Guillaume

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/ namelist entities used as input in Bator

4/ how Bator does read OPERA radar files



Getting observational data from BDMO for atmospheric models (part 1: lists) (Observations)

Tuesday 12 June 2018 by Frank Guillaume

Vous trouverez dans cet article :

  • la liste des des observations (satellites, conventionnelles) extraites (BDMO) par les procédures sur le système SOPRANO, pour la version courante (double et oper) des modèles.
  • Un historique de ces mêmes observations pour les versions antérieures des modèles.
  • Ces listes sont le reflet des requêtes d’extraction utilisées pour les différents modèles telles qu’elles sont formulées.


FULL-POS in the cycle 46 of ARPEGE/IFS. (Diagnostics)

Tuesday 22 May 2018 by Karim Yessad
Table of contents Abstract RESUME Contents This documentation describes the software FULL-POS doing post-processing on different kind of vertical levels. In particular, post-processable variables and organigramme are given. Some aspects of horizontal and (...)


Recommended variable naming in ARPEGE/IFS. (Technical and coding aspects)

Tuesday 10 April 2018 by Karim Yessad
This documentation has for purpose to give a recommended standard root to name meteorological quantities which are used in the model.


CFU (cumulated fluxes) and XFU (instantaneous fluxes) in the cycle 46 of ARPEGE/IFS. (Diagnostics)

Tuesday 10 April 2018 by Karim Yessad
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 46 of ARPEGE/IFS. (Dynamics)

Tuesday 10 April 2018 by Karim Yessad
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 46 of ARPEGE/IFS. (Dynamics)

Tuesday 10 April 2018 by Karim Yessad
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 46 of ARPEGE/IFS. (Dynamics)

Tuesday 10 April 2018 by Karim Yessad
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 46 of ARPEGE/IFS. (Dynamics)

Tuesday 10 April 2018 by Karim Yessad
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 46 of ARPEGE/IFS. (Dynamics)

Tuesday 10 April 2018 by Karim Yessad
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 (...)
