Operational Numerical Weather Prediction (NWP) Output from the Global Atmospheric Part of the Met Office Unified Model (UM)

This dataset contains operational NWP (Numerical Weather Prediction) output from the global atmospheric part of the Met Office global atmospheric Unified Model.

The Met Office Unified Model is the numerical modelling system developed and used at the Met Office (it is run operationally for weather forecasting). It is 'seamless' in that different configurations of the same model are used across all time and space scales.

This model can produce several datasets of which CEDA holds the following:

Met Office Global Atmospheric Model data

Met Office North Atlantic/European (NAE) Mesoscale Model data

The Met Office Global Atmospheric Model has 25 km resolution with 70 vertical levels. It Covers the entire globe and 144 hours in the future twice a day. The Global model provides boundary information for the NAE model, for which additional shorter runs (48 hours) are produced twice a day. The model is kept close to the real atmosphere using hybrid 4D-Var data assimilation of observations. 17km resolution with 70 vertical levels is now also available.

Analyses and first forecast steps are stored to give a time resolution of 1 hour up to 6 hours after each analysis timestep.

The NWP global output archive starts on 1 January 2012, and is ongoing.
