Non-algal portion of the light extinction coefficient

The light extinction coefficient, klk_l, is calculated as a function of the algal density using the nonlinear equation:

kl=kl,0+kl,1α0algae+kl,2(α0algae)2/3k_l=k_{l,0}+k_{l,1}*\alpha_0*algae+k_{l,2}*(\alpha_0*algae)^{2/3}

where kl,0k_{l,0} is the non-algal portion of the light extinction coefficient (m1m^{-1}), kl,1k_{l,1} is the linear algal self shading coefficient (m1(μgchla/L)1)m^{-1}(\mu g - chla/L)^{-1}), kl,2k_{l,2} is the nonlinear algal self shading coefficient m1(μgchla/L)2/3)m^{-1}(\mu g - chla/L)^{-2/3}), α0\alpha_0 is the ratio of chlorophyll a to algal biomass (μg\mu g chla/mg alg), and algaealgae is the algal biomass concentration (mg alg/L).
