Alaska Regional Weather Forecast Model from NCEP

Model runs from the NCEP North American Model for the Alaska region, produced by SCIOPS. Forecasts are generated at 0Z and 12Z, with analysis and predictions every 6 hours extending to 60 hours. The data features a stereographic projection grid of 49 by 35 points at 95.25 km resolution and vertical pressure levels from 1000 to 100 hPa.

Use Cases

• Analyze temporal evolution of atmospheric pressure from 1000 to 100 hPa levels over 60-hour forecast windows.
• Validate model forecast accuracy against observations using the 6-hourly analysis and forecast cycles initiated at 0Z and 12Z.
• Map regional weather patterns over Alaska using the 49x35 point stereographic grid with 95.25 km resolution.
• Study vertical atmospheric profiles by interpolating data across the specified pressure levels.

Strengths

• Forecasts extend to 60 hours with 6-hour temporal resolution.
• Spatial grid defined with 49 by 35 points at 95.25 km horizontal resolution.
• Includes vertical data across pressure levels from 1000 to 100 hPa.

Limitations

• Data recency is limited, with last update recorded in December 2015.
• Specific row counts, file sizes, and column details are unknown.
• Geographic coverage is restricted to the Alaska regional domain.
