Data from the operational NWP (Numerical Weather Prediction) output from the global atmospheric part of the Met Office Unified Model. Analyses and first forecast steps are stored to give an hourly time resolution for 6 hours following each analysis time-step. This archive currently holds data from January 2012 onwards but data will be back populated for earlier years.

Data from the operational NWP (Numerical Weather Prediction) output from the Variable resolution UK (UKV) part of the Met Office Unified Model. This latest configuration of the UM model has a high resolution inner domain (1.5 km grid boxes) over the area of forecast interest, separated from a coarser grid (4 km) near the boundaries by a variable resolution transition zone. This variable resolution approach allows the boundaries to be moved further away from the region of interest, reducing unwanted boundary effects on the forecasts. The UKV model is kept close to observations using 3D-Var data assimilation every 3 hours. This archive is currently being populated at the BADC.

Data from the operational NWP (Numerical Weather Prediction) output from the North Atlantic European (NAE) part of the Met Office Unified Model. The NAE model runs on a grid centred around the UK. Analyses and first forecast steps are stored to give an hourly resolution for 6 hours following each analysis time-step. This archive currently holds data from January 2012 onwards but data will be back populated for earlier years.

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.
