    The GCSolar computer application contains a set of routines that computes direct photolysis rate constants and half-lives of chemical and biological contaminants in the aquatic environment. The half-lives are calculated as a function of season, latitude, time-of-day, depth in water bodies, and atmospheric ozone layer thickness.
