Which radars cover Mertzon?
The closest NEXRAD Doppler radar is KSJT (San Angelo, TX), about 21 miles east-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 Mertzon | View |
|---|---|---|---|
| KSJT San Angelo, TX | 21 mi east-northeast | 1,200 ft | Excellent — the lowest scan sees close to the ground |
| KMAF Midland/Odessa, TX | 93 mi west-northwest | 8,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDYX Dyess AFB, TX | 127 mi northeast | 14,000 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.
