Fitting measured irradiance of Jerlov water types to double exponential functions using R
The distribution of solar radiation in the upper ocean is important for physical modelling, as it is determining the warming of the upper layers by absorption. The solar irradiance measurements from Jerlov, 1976 are approximated by double exponential functions which are to be used in the hydrodynamic model. New improved estimates for the parameters a, g1 and g2 are presented for the classical as well as for different other coastal water types. The goodness of fit and therefore the estimated parameters could be improved by applying the R function nls, hence it is recommended to use the here derived parameters for application within regional modelling of the European coastal waters
