Met Office Global Deterministic 10km on a 2-year rolling archive

Description

A numerical weather prediction forecast for the whole globe, with a resolution of approximately 0.09 degrees i.e. 10km (2,560 x 1,920 grid points). The data is available as NetCDF files. It's offered on a free, unsupported basis, so we don't recommend using it for any critical business purposes.

The global deterministic model is a global configuration of the Unified Model, which is the Met Office’s flagship Numerical Weather Prediction model. The model’s initial state is kept close to the real atmosphere using hybrid 4D-Var data assimilation.

The archive contains data from the past two years. The data is typically available approximately 3 to 6 hours after the model run time.

The following timesteps are available for most parameters:

• every hour from 0 to 54 hours
• every 3 hours from 57 to 144 hours
• every 6 hours from 150 to 168 hours

Update Frequency

The model is run four times each day, with forecast reference times of 00:00, 06:00, 12:00 and 18:00 (UTC).

The runs at 00:00 and 12:00 provide data for the next 168 hours. The runs at 06:00 and 18:00 provide data for the next 67 hours.

The forecast reference time represents the nominal data time or start time of a model forecast run, rather than the time when the data is available.
