Files uploaded from late January 2026 onward will contain changes including:
- precision changes
- new parameters
- changes to existing parameters e.g. adding vertical levels and timesteps
- the height_asl_on_pressure_levels parameter will be replaced by geopotential_height_on_pressure_levels<br><br>
Please check your systems are prepared for these changes.<br><br>

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

The Met Office runs global wave forecast models to support marine safety and operational decision making. Met Office configurations are developed to be run using the community wave model WAVEWATCH IIITM. The global wave configuration is designed to generate accurate forecasts for open waters of the world’s oceans and larger seas. The Met Office wave models are forced using wind data from the Met Office Global Atmospheric Hi-Res Model. The global wave model is run to provide a five day outlook for wave characteristics defining height, period and direction of waves within a given sea-state. The model uses a refined grid system in order to better represent fetch in constrained sea areas and blocking effects of islands and headlands. Please note this is a public beta and therefore a non-operational service.

The Global Ocean component of the Met Office Global Coupled Atmosphere-Land-Ocean-Ice system which has been running in operations since May 2022. The system provides a global physical analysis and coupled forecast products providing 3D daily mean fields of temperature and salinity, zonal and meridional velocities; 2D daily mean fields of sea surface height, bottom temperature, mixed layer depth, sea ice fraction, sea ice thickness and sea ice zonal and meridional velocities; and instantaneous hourly fields for sea surface height, sea surface temperature and surface currents. The Met Office Global Coupled Atmosphere-Land-Ocean-Ice system is comprised of both deterministic and ensemble forecasting systems both of which are coupled to an interactive ocean. Ocean and ice analysis and forecast products are currently generated from the deterministic system once a day with forecast with lead time out to 7 days, interpolated onto a regular latitude-longitude grid products by our Global Ma[...]
