Which radars cover Slater-Marietta?
The closest NEXRAD Doppler radar is KGSP (Greer, SC), about 19 miles southeast. 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 Slater-Marietta | View |
|---|---|---|---|
| KGSP Greer, SC | 19 mi southeast | 1,000 ft | Excellent — the lowest scan sees close to the ground |
| KMRX Knoxville, TN | 93 mi north-northwest | 8,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCAE Columbia, SC | 108 mi southeast | 10,900 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.
