title: Comment on rayleigh-scattering calculations for the terrestrial atmosphere.
abstract: It is shown that, for a given surface pressure, the atmospheric vertical temperature profile has a negligible influence on the Rayleigh optical depth. This contradicts the Bucholtz recommendation for the use of values that vary with air mass type. The influence of atmospheric water vapor amount on the Rayleigh optical depth is also investigated.
