Met Office Blended Probabilistic Forecast: UK and Western Europe 2km Grid

The UK and parts of Western Europe are covered by this gridded probabilistic weather forecast product. It contains 44 parameters including cloud, temperature, pressure, humidity, visibility, precipitation, and wind, derived from the Met Office's operational NWP ensembles and nowcasts. The data is processed and calibrated by the Met Office IMPROVER system and is available in NetCDF format via AWS.

Use Cases

• Generate probabilistic risk assessments for extreme weather events based on forecast probabilities.
• Train machine learning models for weather prediction using the 44 available parameters.
• Analyze spatial weather patterns across the UK and Western Europe based on the 2km resolution grid.
• Calibrate other forecast models using the verified, blended probabilistic outputs.

Strengths

• High spatial resolution of approximately 2 kilometers.
• Contains 44 distinct weather parameters for analysis.
• Forecasts are probabilistically calibrated and verified using spread-skill and reliability checks.
• Data is provided in the standardized, self-describing NetCDF format.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes that some details like the number of sites, parameters, and timesteps may change in the future.
