Dataset
Global NWP meteorological data for Met Office NAME dispersion model (Mk9: July 2015 - 2017)
Abstract
This dataset contains Numerical Weather Prediction (NWP) global meteorological 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. 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 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.
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.

| Access rules: |
Public data: access to these data is available to both registered and non-registered users.
Use of these data is covered by the following licence(s): http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/ When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |
| Data lineage: |
The underlying NWP data is produced by the operational global configuration of the Met Office's Unified Model. The fields are then processed into PP format for use in NAME. Both of these tasks run as part of the Met Office's Operational Suite. The files are then archived into the Met Office's storage system, MASS. Files are then retrieved on the CEDA side using the JASMIN MASS client. |
| Data Quality: |
These data are produced to operational standards at the Met Office.
