Which radars cover Calcium?
The closest NEXRAD Doppler radar is KTYX (Montague, NY), about 21 miles south-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 Calcium | View |
|---|---|---|---|
| KTYX Montague, NY | 21 mi south-southeast | 1,200 ft | Excellent — the lowest scan sees close to the ground |
| KBGM Binghamton, NY | 127 mi south | 14,000 ft | Limited — the beam overshoots the lowest part of storms |
| KENX Albany, NY | 135 mi southeast | 15,300 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.
