Abstract

Data from the operational NWP (Numerical Weather Prediction) output from the Met Office Unified Model. These data are from both the Global and the North Atlantic European (NAE) part of the model. The NAE model runs on a grid centred around the UK. Analyses and intermediate forecast steps are stored to give an hourly time resolution for 6 hours following each analysis time-step. This archive only holds data to January 2012. A new NWP archive is being populated with data from January 2012.

Data lineage:	Data provided by the UK Met Office for archiving at the BADC. Following data transfer issues between the Met Office and the BADC, the Met Office NWP data updates were suspended on 18th January 2012. Archive was closed down. 2019-05-15 These data were removed for the following reason: Data has been removed as it is no longer in use.
Data Quality:	operational NWP output from the Unified Model.
File Format:	Data are pp formatted stored as binary files.
