Met Office UK Deterministic Dataset (Zarr Format)

Description

This dataset is a subset of the Met Office UK Deterministic Dataset, converted from the original NetCDF format into Zarr format for modern data analysis. The Zarr files are packaged as .zarr.zip archives for efficient storage and transfer.

The subset focuses on specific variables and configurations, which are detailed below. Researchers and developers can use this subset for applications in climate science, weather forecasting, and renewable energy modeling.

Zarr Format and Zip Archives

  • Format: The dataset files are in Zarr format, a modern storage format optimized for analytics and machine learning workflows.
  • Packaging: Zarr files are stored as .zarr.zip archives. Each archive corresponds to a specific time interval, such as 2023-01-01-00.zarr.zip.

Subset Attributes

This dataset includes a subset of numerical weather prediction (NWP) variables, categorized as follows:

Accumulated Channels:

  • radiation_flux_in_shortwave_total_downward_at_surface: Downward shortwave radiation flux at the surface (W/m²)
  • radiation_flux_in_longwave_downward_at_surface: Downward longwave radiation flux at the surface (W/m²)
  • surface_roughness: Surface roughness (m) (if available, otherwise null or computed)
  • radiation_flux_in_uv_downward_at_surface: Downward UV radiation flux at the surface (W/m²)

General NWP Channels:

  • temperature_at_screen_level: 2-meter temperature (°C)
  • radiation_flux_in_shortwave_total_downward_at_surface: Downward shortwave radiation flux at the surface (W/m²)
  • radiation_flux_in_longwave_downward_at_surface: Downward longwave radiation flux at the surface (W/m²)
  • cloud_amount_of_high_cloud: High cloud cover (fraction or %)
  • cloud_amount_of_medium_cloud: Medium cloud cover (fraction or %)
  • cloud_amount_of_low_cloud: Low cloud cover (fraction or %)
  • cloud_amount_of_total_cloud: Total cloud cover (fraction or %)
  • snow_depth_water_equivalent: Snow depth equivalent water content (mm)
  • surface_roughness: Surface roughness (m) (if available, otherwise null or computed)
  • radiation_flux_in_uv_downward_at_surface: Downward UV radiation flux at the surface (W/m²)
  • wind_speed_at_10m: 10-meter wind speed (m/s)
  • wind_direction_at_10m: 10-meter wind direction (degrees)

This dataset provides essential meteorological variables for applications in weather prediction, climate modeling, and solar energy forecasting.
