The three wavelengths I've been using for calculations are 615nm, 551nm, and 450nm with corresponding single scattering albedo (SSA) values of .958, .904, and .800. This can be checked with the values you're mentioning and the figure I referenced in post #92. There is some subsequent interpolation that is done when estimating a full spectrum to convolve with the CIE color matching functions. Angstrom exponent is assumed to be -0.05. Would you happen to have SSA values for the three wavelengths I'm using?
Here's my animation of thickening dust with Tau ranging from 0.5 to 10.0. The sun is 45 degrees up. As a more general comment I wonder if there are single scattering phase functions vs wavelength published anywhere? This could help me get the chromaticity better when using the quoted SSA values. For some reason I can tend to show a grayer sky. -------------------- Steve [ my home page and planetary maps page ]
