Model runs from 2015 provide atmospheric forecasts out to 84 hours, generated four times daily at 0, 6, 12, and 18Z. The data is produced by the NCEP North American Model and distributed by the SCIOPS organization via NASA EarthData. It covers North America on a 147 by 110 point grid with a 90.75 km resolution.
Use Cases
- Validate forecast accuracy by comparing predicted pressure levels (1000 to 50 hPa) against observed measurements.
- Analyze temporal patterns of atmospheric variables across the 3-hour forecast intervals from 0 to 84 hours.
- Map and interpolate model outputs for regional studies using the defined Polar Stereographic projection and 90.75 km grid resolution.
- Study vertical atmospheric profiles using data across the specified pressure levels from 1000 to 50 hPa.
Strengths
- Provides forecast outputs at 3-hour intervals for a 84-hour prediction window.
- Spatial grid defined with 147 by 110 points and a 90.75 km resolution.
- Model runs are executed four times per day (0, 6, 12, 18Z), offering multiple analysis cycles.
Limitations
- Temporal coverage is stale, with the last recorded update in December 2015.
- Horizontal resolution of 90.75 km is coarse for localized or high-detail weather analysis.
- Specific data volume, file formats, and available variables are not described.
