Which radars cover Trenton?
The closest NEXRAD Doppler radar is KCAE (Columbia, SC), about 44 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 Trenton | View |
|---|---|---|---|
| KCAE Columbia, SC | 44 mi east-northeast | 3,000 ft | Good — most storms and steady rain or snow show clearly |
| KGSP Greer, SC | 82 mi north-northwest | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCLX Charleston, SC | 88 mi south-southeast | 7,900 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.
