GA 7.1 n216�Scott Wales & Holger Wolff

ARCCSS CMS

Aim:

Reproduce a current high-resolution climate run from the Met Office, as exactly as possible

Uses:

  • Diagnose land surface and CABLE integration issues
  • Enable high resolution Transpose-AMIP runs for CLEX process studies

Source Job & Porting

Based on the GA7.1 HighResMIP run by the Hadley Centre, uses the faster EasyAerosol scheme

NCI site information is in the GA7.1 trunk, porting to Raijin involved minor changes and tuning the decomposition

Model runs at 28 hours per model year, costing 11 kSU per model year

AMIP

One model year complete, scientific validation in progress by Peter Gibson (ARCCSS/UNSW)

Once match with UKMO results is good we will progress to JULES and CABLE bug fixes, running these for longer periods

The aim of these tests is to improve model results for both JULES and the UM, and to show the effectiveness of CABLE

Previous Test

How do we check two model runs with different compilers / libraries are giving the same results?

Run an ensemble with input fields perturbed by 1 ULP for each compiler, check if the results are sampled from the same distribution

Transpose AMIP

Initialise the model from ERA-Interim results at an arbitrary start date

Builds on work done at BoM

Allows for high-resolution modelling of the processes around extreme events
