The ACCESS-AM3 model is a global atmosphere and land coupled model, optionally including the atmospheric chemistry and land biogeochemistry. Some model components, as well as the configurations, are covered by a proprietary licence from the UK Met Office and the Momentum Partnership. As such, they c…

@sonyafiddes , I’ve sent you an invite with read access to the configuration. If you want to save your own configurations to GitHub, then please make your own fork of the repository. If you think a configuration you developed would be helpful to the community and should be considered a standard, su…

Hello, I’d also like to test AM3, including modifying the source code. mosrs: matthewwoodhouse github: matt-woodhouse

@Matt_Woodhouse , you haven’t said which source code you would want to modify. I’ve invited you to the UM and JULES repositories. I’ve also invited you to the ACCESS-AM3 deployment repository so you can follow the recommended building process: Create Prereleases and Releases for an ACCESS Model - AC…

Thanks Claire - will also need access to the UKCA repo if on github!

UKCA is still picked up from MOSRS: ukca_sources=branches/dev/martindix/um13.1_cable_deposition@3051 =branches/dev/martinwillett/um13.1_BlackCarbonRho1900@981 Which means it is going to be harder to build through Spack with a modified UKCA code. Just get yourself acquainted with AM3 a…

UKCA is now a public repo on github if that helps GitHub - MetOffice/ukca: United Kingdom Chemistry and Aerosols

Given you write privileges to the configs. Remember to always push your changes to one of your own branches and then open a pull request if you want to merge your changes back into an existing branch- unfortunately we cannot add branch protections to this repo as it’s private.

Hi, I’m Linyuan, and my GitHub handle is Linyuan-Sun. I have completed the UKMO/MOSRS licensing process and I’m waiting for the account to be activated. I would like access to the ACCESS-AM3 configurations repository to run AM3 experiments. I expect to modify and run configurations first, but also p…

Granted write permissions to the configs repository. As always, please make sure to push your changes to a branch of your own first, before merging back into the core development branches, since we can’t apply branch protections to private repos.

@Linyuan , to be granted access to the source code, you will need to have access to the MetOffice’s GitHub organisation. Please see this post for information on the process.

Note that the process can be slow.
