    "abstract": "This dataset collection contains model data from the Met Office Unified Model (UM) operational Numerical Weather Prediction (NWP) European high resolution model.  This is a regional downscaled configuration of the Unified Model, covering a European domain, with hourly forecast data covering the period T+1 to T+54 hours. With a resolution of approximately 0.04 degrees it is able to produce selected hourly data covering the first 48 hours at surface level and at standard pressure levels four times a day. The model’s initial state is kept close to the real atmosphere by starting from a downscaled global starting condition.\r\n\r\nThis archive currently holds data from April 2016 onwards but data will be back populated for earlier years.",
