Chapter 6.3 Quantitative Description of Radiation
Let’s focus on Irradiance (E) in a portion of the spectrum:
- El = irradiance/unit l interval (W m-2 mm-1)
- El is referred to as the “monochromatic irradiance”
If El is plotted as a function of l as in Fig. 6.2, the area between any two l’s is proportional to the contribution of the radiation in that l band to the total E
