Calculating irradiance penetration into water bodies from the measured beam attenuation coefficientNARA Subscribed
Limnology and Oceanography · 1997 · Vol. 42 · Issue 2 · Wiley
Helgi Arst; Sirje Mäekivi; Toomas Lukk; Antti Herlevi
The relationships between the numerical values and spectral distributions of the downward irradiance attenuation coefficient, K d , λ, and the beam attenuation coefficient, c λ, were investigated. Using experimental data for the Baltic Sea with Secchi disk transparency of 1.5–6 m, we obtained formulae allowing us to determine the spectra of the scattering coefficient in the range of 400–700 nm from data for the beam attenuatio...
