Which radars cover Troy?
The closest NEXRAD Doppler radar is KGSP (Greer, SC), about 62 miles north. 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 Troy | View |
|---|---|---|---|
| KGSP Greer, SC | 62 mi north | 4,800 ft | Good — most storms and steady rain or snow show clearly |
| KCAE Columbia, SC | 68 mi east | 5,400 ft | Good — most storms and steady rain or snow show clearly |
| KJGX Robins AFB, GA | 109 mi southwest | 11,000 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
