Which radars cover Peru?

The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 57 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.

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
