NCEP GFS Weather Model Grid for Hawaii Region

NCEP GFS Model AWIPS 204 (K) Grid provides atmospheric forecast data for the National-Hawaii region. Model runs are produced at 0Z, with analyses and forecasts generated every 12 hours for a 10-day period. The dataset was published by SCIOPS and last updated in December 2015.

Use Cases

• Analyze forecast trends for pressure levels from 1000 to 100 hPa over the 10-day forecast horizon.
• Validate model output against observations using the 160 km resolution Polar Stereographic grid of 93 by 68 points.
• Study surface and height-above-ground variables for the Hawaii region from the 0Z model initialization.
• Correlate atmospheric conditions across the 10 mandatory pressure levels provided in the vertical dimension.

Strengths

• Forecasts are generated every 12 hours for a 10-day period, providing frequent updates.
• Horizontal grid structure is defined with 93 by 68 points at 160 km resolution.
• Vertical coverage includes 10 mandatory pressure levels from 1000 to 100 hPa.

Limitations

• Data has not been updated since 2015, making it temporally stale for current research.
• The 160 km horizontal resolution is coarse for detailed local weather analysis.
• Specific variable names, data formats, and total record counts are unknown.
