These datasets contains Numerical Weather Prediction (NWP) global met data produced by the Met Office Unified Model. The files in the dataset have been processed into a form suitable for use in the Met Office NAME (Numerical Atmospheric-dispersion Modelling Environment) dispersion model, although this dataset may also be of wider use to the academic community as a source of global gridded NWP met data. NAME uses the Met Office Numerical Weather Prediction model outputs as its source for weather data.

The files contain a basic collection of model-level fields (3-d winds, temperature, etc.) and a selection of single-level fields including mean sea level pressure, cloud and precipitation. Fields are split into various geographical regions (referred to as "parts" or "PTs" in NAME) with separate files for each "part". Data are provided at 3-hourly resolution. All files are in packed PP format.
