Which radars cover North Sea?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 24 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 North Sea | View |
|---|---|---|---|
| KOKX Upton, NY | 24 mi west | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KBOX Boston, MA | 97 mi northeast | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDIX Philadelphia, NJ | 126 mi west-southwest | 13,700 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.
