Meetings/UKESM UKCA science advances 2021

Revision as of 10:42, 10 March 2021 by Ptg21 (talk | contribs)

The UKCA Science Management Group, headed by Alex Archibald, and the UKCA Chemistry Working Group are organising a short meeting with the UKESM team to prepare for the forthcoming code freeze (end 2021) in preparation for the development of UKESM2. The meeting is scheduled for Friday, March 26th, 0830-1100 GMT.

The aim is to familiarise the wider community with new code developments, to devise a strategy for the evaluation and assessment of UKESM2 and to identify if groups need help lodging code in the trunk. We anticipate that there will be an evaluation paper of the chemistry module for UKESM2 similar to Archibald et al., 2021 ( to which all contributors of new chemistry code in the UKESM2 trunk will be invited to contribute.
