A new fast clear-sky model called McClear was developed to estimate the downwelling shortwave direct and global irradiances received at ground level under clear … WebMar 1, 2010 · In this paper, we use a simple solar broadband model (Bird and Hulstrom, 1981, Bird, 1984, Bird and Riordan, 1986) to calculate the global irradiance on a horizontal surface under a clear sky in the Lake Rotorua district of New Zealand. The computed clear-sky irradiance was then used to calculate E 0 /E c with solar how to remove grain in premiere pro
