HARMONIE-AROME operational model in Met Éireann#
Met Éireann currently runs the HARMONIE-AROME NWP model on the domain shown below. The operational configuration consists of 1000 x 900 grid points in the horizontal at 2.5 km resolution, with 65 levels in the vertical. The model is run as an ensemble system, called IREPS (the Irish Regional Ensemble Prediction System).
Temporal resolution#
It is a 54-hours forecast with a 1h timestep.
Update frequency#
Every 6 hours starting at 00z the model is executed.
