摘要

In the present article, interrelations between hourly and daily global and diffuse solar illuminance have been developed. By examining a large database, 56 primary locations, of TMY2, it has been found that the values of ratio of hourly global or diffuse illuminance to corresponding daily values, (r_(vt) = I_v/H_v; r_(Vd) = I_(vd)/H_(vd)), are very close to the corresponding values for global and diffuse solar radiation, r_t = I/H ; r_d = I_d/H_d). Thus, it has been proposed that the existing correlations for r_t and r_d be employed to calculate r_(vt) and r_(vd) . The performance of the existing correlations for r_t and r_d to predict r_(vt_) and r_(vd) has been evaluated employing TMY2 data and data of 6 IDMP (International Daylight Measurement Programme) locations. It has been found that the correlation for r_t due to Collares-Pereira and Rabl predicts r_(vt) satisfactorily. Correlation due to Satyamurty and Lahiri for r_d predicts r_(vd) satisfactorily after suitable modification.
