The process used by the SOLAR2000 Professional Grade V2.24 empirical solar irradiance model for determining solar irradiances reported herein is compliant with ISO International Standard 21348: Space Environment (Natural and Artificial) - Process for determining solar irradiances. SOLAR2000 is designated as a type 3 empirical/hybrid model product for solar irradiance spectral categories 6.2 (Total Solar Irradiance), 6.4 (X-rays), 6.5 (Ultraviolet), 6.6 (Visible), and 6.7 (Infrared). A preprint copy of ISO 21348 review can be obtained at the SpaceWx web site.
