Determination of available subsurface light for photochemical and photobiological activity / by J.H. Jerome, R.P. Bukata and J.E. Bruton. : En13-5/89-177E-PDF
"Appropriate determinations of available subsurface light for photochemical and photobiological processes requires accurate estimates of the subsurface scalar irradiation. Quite often only values of downwelling irradiation are available. Therefore, two sets of multiplicative factors are derived. The first set (F0) converts a daily irradiation just above the surface into a daily scalar irradiation Just below the surface. The second set (FZ0) converts an "effective" (i.e. depth-averaged) daily irradiation for a specific photic zone into an "effective" daily scalar irradiation for that photic zone. These multiplicative factors are presented as functions of the subsurface volume reflectance of the water for the volume reflectance range 0.0 to 0.14. For a latitude range appropriate to the Great Lakes, these multiplicative factors vary between 1.1 and 2.1"--Abstract.
