Which radars cover Corona?
The closest NEXRAD Doppler radar is KABR (Aberdeen, SD), about 80 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 Corona | View |
|---|---|---|---|
| KABR Aberdeen, SD | 80 mi west | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 121 mi south | 12,900 ft | Limited — the beam overshoots the lowest part of storms |
| KMVX Grand Forks, ND | 154 mi north | 18,900 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.
