Numerical Weather Prediction (NWP) met data was produced by the operational UKV (United Kingdom Variable-resolution) configuration of the Met Office Unified Model.The files contain a basic collection of model-level fields (3-d winds, temperature, etc.) and a selection of single-level fields including mean sea level pressure, cloud and precipitation from the inner, fixed-resolution domain of the UKV model (this covers the UK area at a spatial resolution of 1.5 km). The UKV model uses a rotated-pole coordinate system.
