title: The backscattering and extinction of visible and infrared radiation by selected major cloud models.
abstract: Volume backscattering functions and optical extinction coefficients are computed for eight suggested major cloud models using the Mie theory for optical wavelengths of 0.488 micro, 0.694 micro, 1.06 micro, 4.0 micro, and 10.6 micro. Results show that there is no clear advantage of one wavelength over another for improving cloud transmission; however, backscattering is significantly reduced at the longer wavelengths. Variations in the optical properties of clouds are also discussed and calculations summarized to indicate the effects of cloud thickness, inhomogeneity, and geographical location on the backscatter function and extinction coefficient.
