This dataset collection contains model data from the Met Office Unified Model (UM) operational Numerical Weather Prediction (NWP) UK high resolution model.

A post processed regional downscaled configuration of the Unified Model, covering the UK and Ireland, is used with hourly forecast data covering the period T+0 to T+120 hours. With a resolution of approximately 0.018 degrees it is able to produce hourly data at surface level and at standard pressure levels up to eight times a day. The model’s initial state is kept close to the real atmosphere using incremental 3D-Var data assimilation.

This archive currently holds data from April 2016 onwards but data will be back populated for earlier years.
