Which radars cover Grantville?
The closest NEXRAD Doppler radar is KFFC (Atlanta, GA), about 18 miles east-northeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Grantville | View |
|---|---|---|---|
| KFFC Atlanta, GA | 18 mi east-northeast | 1,000 ft | Excellent — the lowest scan sees close to the ground |
| KMXX Maxwell AFB, AL | 74 mi southwest | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KJGX Robins AFB, GA | 94 mi east-southeast | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
