The linke turbidity factor based on improved values of the integral Rayleigh optical thickness

Spectral data on extraterrestrial solar radiation, Rayleigh scattering, ozone absorption and absorption by the uniformly mixed gases are critically evaluated and used for computing the integral Rayleigh optical thickness of the clean and dry atmosphere for a given relative optical air mass or solar elevation angle. The results are compared to the corresponding values calculated with the help of the three parameterization formulae. Based on the...
