Which radars cover Greenville?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 66 miles south-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 Greenville | View |
|---|---|---|---|
| KBOX Boston, MA | 66 mi south-southeast | 5,200 ft | Good — most storms and steady rain or snow show clearly |
| KGYX Portland, ME | 110 mi northeast | 11,000 ft | Limited — the beam overshoots the lowest part of storms |
| KENX Albany, NY | 116 mi west | 12,000 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.
