Northern Hemisphere Monthly Surface Pressure Means and Anomalies

Gridded data provides monthly means, long-term monthly means, anomalies, and norms for surface pressure across the Northern Hemisphere. The dataset was created by RIHMI-WDC in 1980, with data originally stored on magnetic tape. It was last updated in December 1991.

Use Cases

• Analyzing spatial patterns of surface pressure anomalies across the Northern Hemisphere grid.
• Calculating long-term monthly pressure norms for climate baseline studies.
• Investigating temporal trends in monthly pressure means for specific grid cells over time.
• Comparing observed monthly pressure means against long-term climatological averages.

Strengths

• Covers the entire Northern Hemisphere with gridded spatial data.
• Includes multiple derived metrics: monthly means, long-term means, anomalies, and norms.

Limitations

• Data is temporally stale, with the last update occurring in 1991.
• The original storage medium was 800 bit/inch magnetic tape, which may present accessibility challenges.
• Specific row counts, column details, and file formats are unknown.
