Which radars cover Denmark?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 72 miles north-northeast. 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 Denmark | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 72 mi north-northeast | 5,900 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 113 mi east-southeast | 11,500 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 142 mi west-northwest | 16,600 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.
