Which radars cover Groton?
The closest NEXRAD Doppler radar is KBGM (Binghamton, NY), about 33 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 Groton | View |
|---|---|---|---|
| KBGM Binghamton, NY | 33 mi southeast | 2,000 ft | Excellent — the lowest scan sees close to the ground |
| KTYX Montague, NY | 88 mi north-northeast | 7,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 117 mi east | 12,200 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.
