The forecasting chain is based on the 18 UTC, ECMWF forecasts at 0.25 degree resolution. The chain comprises the hydrostatic model BOLAM, which is driven directly by the global model, and the non-hydrostatic model MOLOCH (horizontal resolution 0.02 degrees), which is nested in cascade using a 1-way nesting procedure. BOLAM run starts at 18 UTC, MOLOCH is nested at 00 UTC.

MOLOCH domain is smaller than official DPHASE domain. A 48-h MOLOCH forecast is provided daily.

Only a sub-set of TIGGE list is provided (see DS).
