Base/ inherited configuration

UM10.6.1 GA7.1 UKCA Strat+Trop+GLOMAP TS2000 suite u-an114 settings applied to UM10.8 GA7 standard suite:u-ao114 .

UKCA evaluation suite output compared against slighlty different GHG/Trgas settings can be seen here

Deviations from base

• Values for Trace Gases required by UKCA are those specified by the CCMI project for REF-C1/C2 as done for [www.ukca.ac.uk/wiki/index.php/Release_Job_RJ4.0#Initial_conditions_and_forcing_scenario UKCA_Release_Job] (but for 2000/07/01). This uses scenario option for run_ukca, see actual values used under namelist changes below.
  
• Radiation GHG concentrations are fixed for Y2000 as specified for the GC3.1 suite.
• Scaling factor of 1.7 applied to Ocean DMS concentratations (seadms_ems_scaling=1.7) as a proxy for Primary Marine organic aerosol emissions, which is not used in u-an114.

Branches

Note: Branches accompanied by a metadata change will be combined into a [um:log/main/branches/dev/Config Config] branch, a working copy used as the suite's meta= setting and for the runtime STASHmaster.

Additional Branches at UM10.8
[um:log:main/branches/dev/mohitdalvi/vn10.8_cos_mmr_value branches/dev/mohitdalvi/vn10.8_cos_mmr_value]	Sets the initial value of Carbonyl Sulphide (COS) to 1.0e-06 kg/kg for RCP and WMO scenarios. This matches the value being set in all GA7x+Strat+Trop configurations	No

Initialisation

The suite will initialise from a dump produced at the end of a 20-year spin-up run of the GA7.1+Strattrop AMIP run mi-aj670 - /data/d05/hadzm/dumps/aj670a.da20080901_00

Emissions

As described in [wiki:ticket/258/TicketDetails#Emissions here]

Settings (incl. namelist settings)

Y2000 Trace Gas Concentrations

• These have been specified as per CCMI Ref-C1/2 experiment, using a combination of RCP and WMO, same as used in the UM8.4 UKCA Release job.
• The actual values are derived for 2000/07/01 using the Scenario program on PUMA:
  

 ~ukca/bin/scenario 2000/07/01 USER <<< "/home/ukca/tools/scenario/dos2unix/RCP6_MIDYR_CONC_WMO2011_CCMI.DAT"

• The resultant file, supplied to the model is placed at /data/d05/hadzm/ancil/trgas/RCP6_WMO2011_Y2000_CONC.DAT (/projects/ukca-admin/inputs/ancil/trgas/RCP6_WMO2011_Y2000_CONC.DAT on Monsoon).

RUN_Radiation GHG values

• Panel: Sec 01 02 Radiation => Gas MMRs => Varying Gas MMRs: Set l_climcfg=False and then specify these values in the Gas MMRs' panel:
