GLOMAP versions
A 3-month activity in January to March 2019, funded via the JWCRP project ACE (Aerosol and Chemistry Efficiency, PI Dr. Graham Mann, NCAS-Climate, Univ Leeds; co-I Dr. Fiona O'Connor, UK Met Office), involved PDRA Dr. Masaru Yoshioka (Univ. Leeds) consolidating code-changes added by Leeds University researchers in projects during 2015-2018 into "upgrade branches" defining the different versions of the GLOMAP codebase maintained by the core GLOMAP development team at Leeds.
The work successfully consolidated these code-changes into UM branches of the latest version of the UM at that time (UM v11.0), in preparation for lodging these back to the trunk at a subsequent UM v11.x version.
The information on the content of these branches and other details can be found in these two documents -- a brief report for the JWCRP/NCAS-funded activity and a summary poster presented to the UK composition climate modelling meeting in March 2019, with input also from Dr. Adrian Hill at the Met Office :
Following discussion at the UKCA Code Management Group meeting, Mark Richardson created the Table below, to provide the main points from these documents -- and re: the reference GLOMAP versions set out in the GLOMAP software license Media:GLOMAPmode_PET_forECMWFandCNRSlicense_May2021version.pdf
