UK Northern Hemisphere Sea-Level Pressure and 500mb Height Grids, 1944-1946

U.K. Northern Hemisphere sea-level pressure and 500mb geopotential height data from the United Kingdom, processed by the DSS. The dataset contains daily and monthly gridded data, covering the period from December 1944 to December 1946.

Use Cases

• Reconstruct historical weather patterns based on gridded sea-level pressure data.
• Analyze atmospheric circulation changes based on 500mb geopotential height grids.
• Validate or calibrate climate models using historical Northern Hemisphere pressure data.
• Study specific meteorological events within the 1944-1946 timeframe using the daily grids.

Strengths

• Covers a specific historical period from December 1944 to December 1946.
• Contains both sea-level pressure and 500mb geopotential height variables.
• Data has been interpolated to a consistent 5-degree by 5-degree grid for monthly sea-level pressure.

Limitations

• Data is from a single historical period (1944-1946) and may not be representative of other eras.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 1946-12-31 23:59:59.999000; freshness should be verified.
