Which radars cover Trooper?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 54 miles east-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 Trooper | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 54 mi east-southeast | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KDOX Dover AFB, DE | 91 mi south | 8,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLWX Sterling, MD | 138 mi southwest | 15,800 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.
