1-month internal benchmarks
Each update that will introduce a significant change in the full-chemistry simulation is tagged with an alpha version in Git. For each of these alpha versions, the GCST runs an internal 1-month benchmark simulation to isolate the impact from that update.
For more details on the update(s) included in each alpha version and a link to benchmark results, see this Google sheet.
