Where can I find values of absorbtion coefficients and scattering coefficients for air or does anyone know off-hand what they are for stp?

1. Both of absortiopn coeff. and scattering coeff. are not fluid property, but dependent of your system.

2. For air, they are actually zero, because pure O2 and N2 are non-emmiting or non-absorbing species. But, sometimes, they use very small value considering small amount of CO2 and/or H2o in the air.

Sincerely, Jinwook
