MARS run from Previmer restart files (option –run_from_backup)

  • You can make a run from Previmer restart files archived. For example, MANGAE have restart files archived since 2006 (every month now).

  • Configurate backup restart directory in configuration file, section directories:

#backup_restart_dir = '%(operational_dir)s/backup/'
backup_restart_dir = '/home/oo17/previmer/backup'

  • To make MARS hindcast from 02/01/2014 to 03/01/2014, from Previmer archives:

launch_mangae config_mangae.cfg -s 2014-01-02,00:00 -e 2014-01-03,00:00 --run_from_backup

  • A start date is then proposed:

Replay mode
Option run_from_backup : searching the backup date nearest to date : 2014-01-02 00:00:00
Backup found for date 2014-01-01 00:00:00
Do you want to use this date as starting date (yes or no) ?

  • Type yes, save files are copied and jobs are launched.

  • You can for example make a run from archived restart file, and chose output data every 10 mn. Precise output in section rank_1:

[[[output]]]
  time_startout = '00:00:00'
  pasor = 0.25

Warning

The backup date is searched 30 days around the given date. If you have the message No Backup found near date 2006-03-01 00:00:00, aborting, do not hesitate to check restart dates in /home/oo17/previmer/backup
