Abstract We have investigated several methods of incorporating laboratorymeasurements of effective cross-sections (quantum yield timesabsorption cross-section) that are non-linear functions oftemperature, pressure, and wavelength, into the Fast-J photolysis codeof Wild et al. (2000). The best method was found to beparameterization of the solar weighted effective cross-section usingthe form of the effective cross-section, with numerical fitting of theparameterization constants. Using this technique on the acetone dataof Gierczak et al. (1998) produces aparameterization which fits all points to within 1%. This methodshould also benefit other photolysis codes with large wavelength bins.
