| The scene observed in false color illustrates the incident light pattern so explicitly as to delineate irradiance isopleths. |
| In the preillumination experiments the cells were exposed to lights of different irradiance, dose and direction. |
| Although the solar simulator provides a higher spectral irradiance throughout the UV, its spectrum differs from natural sunlight. |
| This irradiance and the radiance in the opposite direction were then inserted into equation to calculate the ideal reflectance. |
| From these values the integrated irradiance values are obtained for the desired time interval. |
| Depletion of the Earth's ozone layer is considered responsible for an increase in the solar ultraviolet irradiance reaching the surface. |
