  • BATOR’s Changes and input files used
    5 May 2021, 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 (in french only)

    4/ how Bator does read OPERA radar files

  • For an efficient assimilation of OPERA radar data, Feb. 2020
    14 February 2020, by Patricia

    This document describes the choices made at Météo France in order to efficiently assimilate OPERA radar data, using the metadata and the quality
    flags existing in the files available on the OIFS (OPERA Internet File System).

    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.

  • OBSTAT documention
    4 June 2008, by Paul Poli

    This documentation was written by Paul Poli in April 2006 and is regularly updated since then.
    Abstract The OBSTAT software computes and plots statistics on observations assimilated in the ECMWF or Meteo France assimilation suite. One common application of OBSTAT is to produce statistics of observation minus background and observation minus analysis quantities. One assimilation time period is sufficient to run OBSTAT, but statistics over several assimilation time periods can be cumulated (...)
