Description of the upgrade

A change was made to include:
  • introduction of vertically non-interpolating semi-Lagrangian scheme and smaller time filter;
  • suppression of inversion clouds at the lowest three model levels rather than just the lowest level;
  • introduction of a prognostic equation for sea-ice temperature to replace the use of climatological values;
  • other minor parametrization changes.
