What does the extinction coefficient describe?
What will be an ideal response?
The extinction coefficient is the parameter used to quantify the attenuation or
exponential reduction of radiation through a gas or vapor. It is the exponent of
the exponential function and is usually modelled as dependent on the partial
pressures of the various gas components. Water vapor and carbon dioxide seem
to strongly affect the extinction coefficient and therefore the radiation
attenuation.
