- ecCodes now supported. Previous versions did not work with ecCodes.
- modified SETTLS scheme for improved stratospheric warming forecasts and various improvements for the semi-Lagrangian interpolation and mass fixers (see below).
- fix to bug in qnegat.F90 where negative values of moisture were not reset correctly, leading to a very slow moistening of the atmosphere. Negligible difference for medium range forecasts.
- setup routine for coupled runs now added (was missing in previous version).
- bugfix to cptime.F for RS7K architecture (with thanks to Siham SBII, Morocco).
- new command createEX available to create the experiment directory structure for single or ensemble forecasts (see User guide for more details).
- some I/O statistics (from iostream_mix) are now reported correctly in the model log file (NODE.001).
- minor efficiency improvements.
- some surplus code removed.
