Abstract
Three models of spectral direct irradiance of the sun at the ground are compared with experimental spectral measurements. Satisfactory agreement is obtained although their behavior is quite different mainly in the absorption bands. The turbidity parameters required by the model are obtained from the measured data and the water vapor by simultaneous radiosondage.
