Experimental setup

Overview

Two suites are used: a control (au-aa427) and a trial run without IASI observations (au-aa???). Both suites are based on APS2 ACCESS-G Rose suite, au-aa068 at r1316.

  • Resolution: N512L70
  • PFM resolutions: N108/N216
  • Observation types used,

Used the latest version, v408. Some of the changes are,

MTSATClear_stlist.nl - since the names, 'DayStart?' and 'DayEnd?' are not valid in OPS30.0.0 I commented out the lines; Q. What would be the effect????

ToDo Use stationlist file from au-aa094 as a starting point. You may need to copy stationlist files from Jasmin mirror to ~access/da as the files may need modification

Preparing Bufr files

Bufr files copied: 20150718 00Z till 20151031 18Z

Archiving

  • Model forecast files are archived to ????
  • SatRad writefiles are archived to ????

Luke-warm start

  • start dump (iau-start-dump) from 20150717 12Z
  • analysis increment (an_inc) from 20150717 18Z
  • soil moisture (an_smc) from 20150717 18Z
  • bgerr (bgerr.new) from 20150717 18Z
  • all the warm-running files are from pre-operational APS2 ACCESS-G, saneg.

Spin-up run

  • Only control suite does the spin-up as the same warm-cycling files will be fed to the trial suite
  • The spin-up starts from 20150717 18Z and finishes 20150731 18Z
  • Then the bias coefficients are updated.
  • The suite restarts from 20150801 00Z and finishes 20151031 18Z
