-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](Data#suspended-solids)). 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).
