Extract data from Previmer database (Section previmer)ΒΆ

  • This section extracts data from Previmer database

  • If this section is not in your configuration file

  1. Download it from svn and add it in you configuration file

svn checkout https://forge.ifremer.fr/svn/previmerchainop/trunk/formation/

service7>693% pwd
/work/lpineaug/FORMATION_CHAINOP/formation
service7>694% ls
section_previmer.cfg  section_wave.cfg

  1. Add previmer in your treatments, section treatments

[treatments]
  #list = ['meteo', 'obc', 'river', 'rank_0', 'rank_1', 'format_oco','demerliac','mirror_copy','finalize']
  list = ['meteo', 'obc', 'river', 'rank_0', 'rank_1','format_oco','demerliac','mirror_copy','finalize','previmer']

  1. Add previmer directory in section directories

[directories]
  previmer_dir = '%(operational_dir)s/inputs/'

  • To extract data from Previmer database, launch previmer:

launch_mangae config_mangae.cfg -s 2014-01-01,00:00 -e 2014-01-03,00:00 --only previmer
  • To follow if the run is OK

    • check if previmer is OK in f1-mangae.xml

    • in case of problem, check the log file ./logs/MANGAE2500-r1630/20140101_20140103/previmer.log

  • Output file : ./inputs/MANGAE2500-r1630/previmer/MENOR.nc

  • List of files that have been concatenated: ./inputs/MANGAE2500-r1630/previmer/PREVIMER_F2-MARS3D-MENOR1200_files.txt
