teorological optical range, MOR), precipitation intensity, and precipitation type. Light scatters
from particles whose diameter is in the order of magnitude of the wavelength of the light and the
amount of scatter is proportional to the attenuation of the light beam. The extinction coefficient
is defined with the following equation,
s(1=km) = 3000=MOR
where MOR (Meteorological Optical
