Data coverage
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
