How well can the network see Coronado?
The nearest Doppler radar is KNKX (San Diego, CA), 19 miles to the NNE. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Coronado its center is about 1,100 ft above ground. That is about as close as radar coverage gets in the United States: the lowest scan is still near the ground when it reaches Coronado, so low-level rotation and the leading edge of a gust front show up on it. Coronado is closer to its radar than 86% of US cities.
The closest instrument actually measuring the air is KNZY · San Diego/North Island NAS on the ASOS/AWOS network, 3.9 miles away. Close enough that its readings are, for practical purposes, the conditions in town.
Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the center of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the California observing network as of this build.
