A global configuration provides the large-scale weather forecast and also supports the nested higher resolution regional models with boundary data. More detailed short-range forecasts are provided by these high-resolution models which are able to represent certain atmospheric processes more accurately, as well as having a more detailed representation of surface features such as coastlines and orography.

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

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 is used. With a resolution of approximately 0.018 degrees are 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.

Data lineage:

New data repository of the UK Met Office wholesale NWP data at CEDA.
Following data transfer issues between the Met Office and the BADC, the Met Office NWP data updates were suspended on 18th January 2012. A new data transfer route was established and at the same time, CEDA-BADC decided to revamp the entire NWP archive and created a new NWP archive. This new archive is essentially a mirror of a subset of the NWP archive at the Met Office (as extracted from the Met Office Archive Storage System (MASS)).

Data Quality:
See dataset associated documentation.
File Format:
Data are GRIB formatted.
