1.1 These tables define an air mass 1.5 solar spectral irradiance distribution for use in all solar applications where a standard terrestrial spectral irradiance is required for that part of solar irradiance, diffuse, and direct, that is incident on a sun-facing, 37°-tilted surface. A similar standard for direct normal irradiance is given in Standard E891. 1.2 These tables are modeled data that were generated using a zero air mass solar spectrum based on the revised extraterrestrial spectrum of Neckel and Labs (1), the BRITE (3, 4) Monte Carlo radiative transfer code, and the 1962 U.S. Standard Atmosphere (5) with a rural aerosol (6, 7, 8). Further details are presented in Appendix X1. 1.3 The air mass zero (AM0) spectrum that was used to generate the terrestrial spectrum was provided by C. Frohlich and C. Wehrli (1) and is a revised and extended Neckel and Labs (2) spectrum. Neckel and Labs revised their spectrum by employing newer limb-darkening data to convert from radiance to irradiance, as reported by Frohlich (9), citing the study by Hardrop (10). Comparisons by Frohlich with calibrated sunphotometer data from Mauna Loa, Hawaii, indicate that this new extraterrestrial spectrum is the best currently available. 1.4 The development of the terrestrial solar spectrum data is based on work reported by Bird, Hulstrom, and Lewis (11). In computing the terrestrial values using the BRITE Monte Carlo radiation transfer code, the authors cited took the iterations to 2.4500 [mu]m only. We have extended the spectrum to 4.045 [mu]m using sixteen [lambda]i values from the original Standard E892-82. Irradiance values in Standard E892-82 were computed from the extraterrestrial spectrum represented by Standard E490. The additional data points were added to account for the solar irradiance in this region that account for approximately 1.5% of the total irradiance between 0.305 and 4.045 [mu]m. The errors propagated by doing so are insignificant. 1.5 An air mass of 1.5, a turbidity of 0.27, and a tilt of 37° were chosen for this standard because they are representative of average conditions in the 48 contiguous states of the United States.
