- 100km MOM6-CICE6-WW3 OM3 nearing release
- 100km MOM6-CICE6-WW3 OM3 load balancing complete
- 25km + 100km OM3 performance optimisation underway - gains of ~10% with MOM6 code changes and compiler directives
- implementation of river runoff spreading nearing completion
- code changes underway (splitting JRA55 runoff into river and basal melt) to allow basal melt to be input at depth, also accounting for latent heat
- 25km OM3 test4 assessment (all the evaluation for the latest ACCESS-OM3-25km test4 run here) highlights areas that need improvement (details here)
- thermocline too deep,
- weak southern hemisphere heat transport,
- SSS too fresh,
- poor Kuroshio and Gulf Stream separation and variability distribution,
- incorrect North Atlantic deep convection locations,
- weak and declining NADW,
- excessive Mediterranean outflow.
