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.

• Aditional statistics:
  1. ???? need to turn on SatRad NetCDF writefiles for o-b statistics
  2. ???? need to turn on o-a statistics from VAR

Preparation of configuration

rose-suite.conf

Change CONF_START and CONF_STOP

set_ops_stationlist.ksh

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

set_ops_screen_stationlist.ksh

set_ops_control_files.ksh

set_ops_bias_files.ksh

ODB and OPS versions

ODB_VERSION is odb30.0.2 OPS version is 30.0.0

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
