Data coverage
A numerical weather prediction model that produces forecasts for the whole globe up to a week ahead. The projection used is the Equirectangular Latitude-Longitude and the grid resolution is 20km. 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. Met Office Global Ensemble Prediction System (MOGREPS-G) is a global configuration of the Unified Model, which is the Met Office's flagship Numerical Weather Prediction model. The archive contains 30 days of data. The data is typically available approximately 10-11 hours after the model run time. The following timesteps are available: - Every hour from 0 to 54 hours or from 0 to 132 hours (depending on the parameter) - Every 3 hours between 57 to 198 hours or from 135 to 198 hours (depending on the parameter) for data prior to late January 2026. Data produced after this run out to 246 hours.
