Ported Unified Model Version 5.5 Software from the Met Office


This dataset contains Version 5.5 of the Ported Unified Model Software (PUM) from the UK Met Office. This allows the Unified Model to be run on a user's own system. This is currently the most up-to-date version available of the PUM supersededing version 4.5. The archive also contains community contributions associated with the PUM5.5.

The Unified Model is the name given to the suite of atmospheric and oceanic numerical modelling software developed and used at the Met Office. The model supports global and regional domains and a wide range of temporal and spatial scales that allow it to be used for numerical weather prediction as well as a variety of related research activities. This software allows the Unified Model to be run on a user's own system. More information detail about the Ported Unified Model Version 5.5 is available on the Met Office PUM5.5 web page.

Please note that this is the MODEL SOFTWARE ONLY, not the UM model output, which is at http://badc.nerc.ac.uk/um/

What's New?

The PUM (Ported Unified Model) version 5.5 source code is now available as a new dataset from the BADC for registered PUM5.5 data users.

Restricted source code

Access to Met Office PUM 5.5 source code at the BADC is restricted to UK Academic Researchers only. Non-UK researchers must apply directly to the Met Office for access to the code. The application for access to the Met Office Ported Unified Model Software includes the Met Office Agreement to be signed and returned to BADC.You will then be given access to these datasets via a Web account. Details of your account will be sent by e-mail.

Access to the source code

The PUM 5.5 source code is stored in the software directory beneath /badc/ukmo-pum5_5/. If you would like to receive the data on CD-ROM or DVD formats then please contact BADC Support (restricted to users who have been granted access to the code).


Detailed documentation about the PUM 5.5 is provided with the source code.


Who to Contact

General queries about these pages and access to the data should be directed to the BADC support line. Your query should be answered within one working day. When follow-up work is required, the BADC support will carry out the work as quickly and efficiently as possible, and in any case, the user will be kept informed of progress.

For technical queries regarding the model itself, please contact the dedicated support group at the UK Met Office directly (portable_um@metoffice.gov.uk)
