The volume contains appendixes related to the computation of photolytic rates for the UNC chamber. The first appendix is the data base of climate and solar radiation variables needed by the models, including time of day, air pressure, total column ozone, total column water vapor, relative humidity, aerosol type, aerosol optical density at 500 nm, and the spectral albedo of the aerosol. The second appendix gives plots of broad band model predictions by the models compared with observed TSR and UV irradiance data for each day in the UNC data base, and includes selected examples of plots of the predicted NO2 and HCHO-to-radicals photolysis rates inside the chamber. The third appendix lists the molecular absorption cross sections and reaction quantum yields used in the photolysis rate calculations. The final appendix includes listings of the computer code for all models and sub-models. These models run on MS/PC-DOS type machines and are available on diskettes from the authors for distribution costs. The in-chamber photolysis rates for twenty species, computed every 16 minutes for each day in the UNC data base are also available on diskettes for distribution costs.
