Which radars cover Glenolden?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 47 miles east. 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 Glenolden | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 47 mi east | 3,300 ft | Good — most storms and steady rain or snow show clearly |
| KDOX Dover AFB, DE | 75 mi south | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLWX Sterling, MD | 133 mi west-southwest | 15,000 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.
