Astronomical and Actinometric Values of Standard Atmospheric Transmittance
Analysis of data on the optical properties of the real cloudless atmosphere allowed us to propose as a standard of average conditions the Shifrin-Minin radiation model of the atmosphere . With this model, we can calculate all of the necessary characteristics of the radiation field using the values of only three parameters: the optical thickness of the atmosphere τo for a given wavelength, the meteorological visibility So for the same wavelength, and the amount of precipitated water W. The radiation field is very sensitive to τo, which characterizes the aerosol turbidity of the atmosphere.
