NEXRAD range in clear air mode is approximately how many nautical miles?

Explanation:
Clear-air mode increases the radar’s sensitivity to pick up faint returns when there isn’t heavy precipitation, so the system can detect targets farther away. For NEXRAD, this higher sensitivity yields an approximate maximum range of about 248 nautical miles. That value sits just under 250 NM and can vary with scan settings and atmospheric conditions. In comparison, precipitation mode is limited to roughly 230 NM because heavy rain attenuates the signal. So 248 nautical miles is the best approximate range for clear-air operation.
