On the computation of the actinometric radiation field

Abstract

In a previous work we have shown an algorithm (J, m, w, B, a= 1.5) which describes the Actinometric Radiation Field; given as initial conditions three of the above variables one obtains the fourth variable. In the present paper a more flexible algorithm is presented. The method enables one to make a quantitative analysis of the different solar constant distributions together with the transmission functions used. Results show these relationships for combinations of the input functions in terms of an indicator of the whole computation process, in this case, the atmospheric turbidity coefficient B. The algorithm becomes a useful technique for any desirable combination of the spectral irradiant curves together with the given transmission functions; in this way, the International Commissions may choose the best combination and recommend it for future calculations.
