These datasets contain Numerical Weather Prediction (NWP) global meteorological data produced by the Met Office Unified Model. The datasets have been processed into a form suitable for use in the Met Office NAME (Numerical Atmospheric-dispersion Modelling Environment) dispersion model. NAME uses the Met Office Numerical Weather Prediction model outputs as its source for weather data to be able to predict movement of atmospheric parcels forwards and backwards in time.

The NWP data used by NAME is different from other forms of Met Office NWP as follows:
- It has been split into spatial partitions (i.e. different parts of the world/domain are in different files)
- It has been reformatted into PP format

However, from the perspective of the raw data, this dataset of global gridded NWP meteorological data is generically useful for a whole range of scientific research and applications.
