Notes of the code management group meeting 21/3/2013

Notes from code managment meeting held 21/3/2013 in Cambridge

This meeting covered two main issues: the release of a shared job at 8.4 and plans for lodging code in the next 12 months.

Getting to a shared release

1. The prefered job will be a N96L85 job based on Global Atmosphere 4 (paper submitted to GMDD).
2. It will use the CHEST chemistry scheme with the ASCHEM extention if possible and the stratospheric version of GLOMAP-Mode.
3. The fallback if this does not work is the ACHEM chemistry and GLOMAP-mode without the aerosol extensions
4. The CHET chemistry version can still be used for development but is not to be the released job
5. The planned timeline is:
   1. End of May - configuration ready to be run for 1 year to generate input to evaluate suite.
   2. Mid June. Luke to do actual model run and run the evaluation suite.
   3. End of June - Alex to look at chemistry results from evaluation suite and Graham to look at aerosol results and use a Red-Amber-Green system to rate them. Red means it is not suitable for doing any science with at the present time. Amber means there are still some issues but if these are documented, they should not prevent its use for peer reiviewed publications. Green would be the best results we have so far seen from UKCA.
