MARS hindcast (new option –replay, from far better than –step!)

  • For MARS hindcast, option –replay allows to make runs by block. You must specify the number of days for each block run_duration, the date start date_start and date end date_end.

  • To make MARS hindcast from 01/01/2013 to 01/01/2014, with block every 30 days, add replay section in your configuration file :

#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
# Section replay
# Configuration des rejeux
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[replay]
  active = False
  date_start = '2013-01-01,00:00'
  date_end = '2014-01-01,00:00'
  run_duration = 30
  reference_config = 'config_mangae.cfg'
  relaunch_cmd = 'launch_mangae config_mangae.cfg --replay'
  final_treatment = 'finalize'

Warning

Take care to have the same config file name in reference_config and relaunch_cmd !

  • To launch MARS hindcast :

launch_mangae config_mangae.cfg --replay

  • All treatments of the first block (1/01/2013-31/01/2013) are launched

  • To follow if the run is OK

    • check if sections are OK in configuration file f1-mangae.xml

    • in case of problem, check the log files ./logs/MANGAE2500-r1630/20140101_20140131/*.log

  • If first block is OK

    • Configuration file for this first block will be copied in ./logs/MANGAE2500-r1630/20130101_20130131/f1-mangae.xml, there is one log directory for each block

    • Output files: MARS results will be in results directory ./res/MANGAE2500-r1630/PREVIMER_F1-MARS3D-MANGAE2500/20130101_20130131, there is one results directory for each block

  • At the end of first block, date_start is automatically change in configuration file, and second block starts:

date_start = '2013-01-31,00:00'

  • After second block, third block starts…and so on…until end date

  • To know in which block run is, just check head of configuration file :

Run from 2013-01-01 00:00:00 to 2013-01-31 00:00:00

Warning

By default, saverestart_step is at 1 in paraspec.txt.ref. Do not forget to change it for long hindcast ! You can for example give the value of run_duration

[[[paraspec]]]
  saverestart_step = 30.0

  • Jobs specified in treatments section are launched.

If treatments section is:

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

Jobs that are launched are:

  • meteo : Preparation of meteorological forcings for ranks 0 & 1

  • obc : Preparation of open boundaries conditions

  • river : Preparation of river forcings

  • rank_0 : MANGAE config, run Mars rank 0

  • rank_1 : MANGAE config, run Mars rank 1

  • format_oco : Format rank 1 outputs to OCO norm

  • demerliac : Demerliac filtering of hourly data

  • mirror_copy : Copy results files to mirror directory

  • finalize : Finalize the operational execution
