Tables of the Refractive Index for Standard Air and the Rayleigh Scattering Coefficient for the Spectral Region between 02 and 200 μ and Their Application to Atmospheric Optics

The refractive index of standard air has been tabulated for the range 0.2 to 20.0 μ, namely, 0.2(0.01)0.8; 0.8(0.1)2.0; 2.0(0.5)10.0; 10(1)20 μ. The values are based on Edlen’s formula. For computations of Rayleigh scattering, the scattering cross sections, the mass and volume scattering coefficients have been tabulated for the same values of wavelength as for the refractive index. The optical thickness and the transmissivity of the standard atmosphere is given next, and finally, the mean scattering coefficient for visual observations which is βv=1.23×10−7 (cm−1).
