A global configuration of the Met Office Unified Model provides the most accurate short range deterministic forecast by any national meteorological service covering a six day period. With a resolution of approximately 0.234 x 0.153 degrees, it is able to produce selected hourly data covering the first 48 hours at surface level and at standard pressure levels twice a day. The model’s initial state is kept close to the real atmosphere using hybrid 4D-Var data assimilation.

This dataset contains model data from the Met Office Unified Model (UM) operational Global Numerical Weather Prediction (NWP) model. The archive currently holds data from April 2016 onwards but data will be back populated for earlier years.

Use of these data is covered by the following licence: When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record.
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.
