Which radars cover Nassau Lake?
The closest NEXRAD Doppler radar is KENX (Albany, NY), about 23 miles west. 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 Nassau Lake | View |
|---|---|---|---|
| KENX Albany, NY | 23 mi west | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KOKX Upton, NY | 122 mi south-southeast | 13,000 ft | Limited — the beam overshoots the lowest part of storms |
| KBGM Binghamton, NY | 124 mi west | 13,300 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.
