Range Description
A Strong haze, visibility 5km; or strong sunlight, severe heat shim-
mer
B Light haze, visibility about 20km; or moderate sunlight, slight heat
shimmer
C Overcast, no haze, visibility about 40km; no heat shimmer
Measurements can be made to reflector tapes over the entire range without external ancillary
optics.
Accuracy refers to measurements to standard prisms.
