Absorption coefficient is defined by the position, strength, and shape of a spectral line: k a, = S f( – 0) [7.1] where S in the line intensity and f is the line profile: S ka, d and f( 0)d 1 THE absorption spectrum of water in the visible region has been widely investigated^1-9 because of the basic, technological and environmental importance of liquid water. Despite these efforts, there are significant disagreements between experimental results: discrepancies of factors of ~2 in the absorption coefficients are not uncommon between various data. Possible reasons for the The absorption coefficient, or rate at which incident radiation decreases with depth, is about 0.1 cm-1 for snow and only 0.001 cm-1 or less for clear ice.

Absorption and scattering coefficients. When a narrow beam passes through a volume, the beam will lose intensity due to two processes: absorption and scattering. Absorption coefficient of a volume, denoted μ a, and scattering coefficient of a volume, denoted μ s, are defined the same way as for attenuation coefficient. by the logarithm of this ratio presented in decibels.
