FIGURE 11.1
Solar spectrum at the top of the atmosphere (upper curve) and at sea level (lower curve). Shaded areas indicate absorption of radiation by atmospheric molecules. The dashed curve is the radiance spectrum of a black body heated to 5,900 K, scaled to the solar irradiance curve at the top of atmosphere. (Data from Valley, S.L., ed. Handbook of Geophysics . Bedford: U.S. Air Force,
1965.)
