12、17801:2014(E) Introduction The effect of solar radiation on surface of the earth (global radiation) is the most important primary weathering factor. The photons absorbed by the molecules during radiation exposure are often sufficient to split chemical bonds, start photochemical reactions and cause a
13、n electron transfer 1 . The spectral irradiance of the solar radiation is variable locally and in time. A reference spectrum is therefore required as a basis for the simulation of the spectral irradiance of solar radiation with artificial radiation sources/radiation systems. Data of the CIE (Commiss
14、ion Internationale de Lclairage) Publication (No. 85, 1989) have been used as a basis for years. Table 4 specifies the spectral irradiance of global radiation (direct and diffuse radiation) for a cloudless sky, zenith position of the sun by day and night comparisons at the equator at sea level. But
15、in CIE 85, the data of the global solar irradiance only begins at 305 nm, the step width is very rough and the calculation code got unexplainably lost. Therefore, there have been efforts to revise CIE No. 85 for many years. The new Table 1 gives modelled data (using the SMARTS model version 2.9.2) g

17、ctrum to the field of weathering degradation (see Table 1) in order to classify solar simulators in the UV, visible and infrared wavelength range. The photochemical ageing which occurs in practice is simulated with time compression in laboratory weathering instruments by sequencing maximum stress cl
18、imate episodes. To give a spectral irradiance target, the table specifies the spectral irradiance of global radiation (direct and diffuse radiation) with a cloudless sky, zenith position of the sun by day and night comparisons at the equator at sea level as defined in Table 4 of CIE No. 85 .This is
19、a realistic maximum exposure under representative clear sky conditions. The data contained in Table 1, Figure 2, and Figure 3 were generated using the SMARTS2 Version 2.9.2 2 3to recalculate the CIE No. 85, Table 4. Table 2 contains the original data from CIE No. 85, Table 4. The numbers are shown i

The more atmosphere through which it passes, the greater is the attenuation. 4 Reference global solar spectral irradiance at sea level The reference global solar spectral irradiance for air mass 1.0 (illustration see Figure 1) is given in Table 1 and Figure 2 and Figure 3.
