Which radars cover Belmont?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 30 miles south. 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 Belmont | View |
|---|---|---|---|
| KBOX Boston, MA | 30 mi south | 1,900 ft | Excellent — the lowest scan sees close to the ground |
| KGYX Portland, ME | 113 mi north-northeast | 11,700 ft | Limited — the beam overshoots the lowest part of storms |
| KOKX Upton, NY | 137 mi southwest | 15,700 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.
