Pazan's U.S. Navy Northern Hemisphere Sea-Level Pressure Grids consist of daily pressure data on a 63x63 polar-stereographic grid. The dataset covers a 33-year period from January 1946 to December 1978. The grids were produced by Steve Pazan at the U.S. Navy Fleet Numerical Oceanography Center.
Use Cases
- Analyze temporal trends in daily sea-level pressure values across the 63x63 grid over 33 years.
- Correlate grid pressure patterns with historical storm tracks or climate indices like the North Atlantic Oscillation.
- Validate the accuracy of modern climate model simulations against this historical pressure grid data.
Strengths
- 33 years of continuous daily data from 1946 to 1978.
- Spatial data is structured on a consistent 63x63 polar-stereographic grid.
Limitations
- Data is over 45 years old, ending in 1978, limiting analysis of recent climate trends.
- Spatial resolution is coarse (63x63 grid), which may not capture local pressure features.
- The dataset's provenance and processing methodology from the original Navy source are not detailed.
