How well can the network see Topeka?
The nearest Doppler radar is KTWX (Topeka, KS), 29 miles to the W. 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 Topeka its center is about 1,800 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 Topeka, so low-level rotation and the leading edge of a gust front show up on it. Topeka is closer to its radar than 72% of US cities.
The closest instrument actually measuring the air is KTOP · Topeka/Billard Muni on the ASOS/AWOS network, 4.5 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 Kansas observing network as of this build.
