  • 25km OM3 test4 assessment continuing - please join in to ensure that the model will work well for your areas of interest!
  • 25km OM3 test5 in preparation
    • C-grid CICE
    • horizontal runoff spreading
    • basal melt latent heat
    • numerical mixing diagnostic
    • bathymetry fixes
    • tripole fixes
    • code updates, bug fixes, performance optimisations, etc.
  • WOMBATmid code and documentation complete; parameter optimisation underway
  • Method for cycling OM3 runs under development
  • MCW 100 km ERA5 config: aiming for a beta release; long-run underway, to be presented at AARC next week (slide).
