Hemispheric Meteorological Grids and Analysis

National Meteorological Center gridded data for both Northern and Southern Hemispheres. The dataset contains 145 x 37 global grids for all atmospheric levels, stored in a binary packed format. It was produced by NOAA NCEI and last updated in April 1997.

Use Cases

• Analyze hemispheric-scale atmospheric patterns using the 145 x 37 global grid structure.
• Unpack and convert scaled halfword integer data back to floating-point meteorological fields for historical studies.
• Compare Northern and Southern Hemisphere conditions using the separate octagonal Mercator and polar stereographic grids.

Strengths

• Covers both Northern and Southern Hemispheres with separate grid projections.
• Provides 145 x 37 global grid resolution for all atmospheric levels.

Limitations

• Data format is a legacy binary packed structure requiring specific unpacking knowledge.
• Temporal coverage is unclear and the dataset has not been updated since 1997.
• Sample size and specific variable fields are not described.
