Actinic flux (relative units)

FIGURE 3.24 Calculated relative actinic flux using best estimate albedos as a function of height above the earth's surface for solar zenith angles 0 of 20, 50, and 78°, respectively, at (a) 332.5, (b) 412.5, and (c) 575 nm [from Peterson (1976) and Demerjian et al. (1980)].
