-The extinction coefficient ($`k_{d}`$) is depending on the amount of Total Particulate Matter (TPM) in the water that varies over the season (described by cosine function). The extinction coefficient is calculated from the TPM concentration using a simplified version of the function that is used by Los and Wijsman (2007), based on Van Gils and Tatman (2003).
