| Imaginary part of the refractive index of desert aerosol | Parent topic |
Fig. 1. Imaginary part, m", of the complex refractive index of refractive index of m = m' - m"i, of three samples of desert aerosol, each collected over a period of 10 days in southern New Mexico (Lindberg and Laude 1974). The values shown here were obtained using Eq. 3 in Refractive index: Introduction with the "absorption coefficient" obtained by applying the Kubelka-Munk theory of diffusive reflectance (for example, Kortüm 1969) to samples of the dust diluted in BaSO4. That coefficient is about 2 times greater than the absorption coefficient defined in relation to the Lambert law (Lindberg and Laude 1974). Hence, the values shown (see also a data file) here are 1/2 of those listed by Lindberg and Laude. The accuracy of the measurement of m" has been estimated by those authors at 25%. The green vertical line at 0.44 µm shows a range of m" obtained for Saharan aerosol by radiative theory modeling of sun radiometer data (Tafuro et al 2006).
