Which radars cover Sierraville?
The closest NEXRAD Doppler radar is KRGX (Reno, NV), about 49 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 Sierraville | View |
|---|---|---|---|
| KRGX Reno, NV | 49 mi east-northeast | 3,500 ft | Good — most storms and steady rain or snow show clearly |
| KBBX Beale AFB, CA | 68 mi west | 5,400 ft | Good — most storms and steady rain or snow show clearly |
| KDAX Sacramento, CA | 103 mi southwest | 10,000 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.
