“…Rather than descending into the complexities of further analysis, we have included the proposed mechanism modifications into box model simulations of the local photochemistry taken from outputs of the Lawrence Livermore National Laboratory 2-D diurnally varying model of the atmosphere. 18 This method is the simple and sure way to examine effects. The photolysis rates, kinetics rate constants, 19 species concentrations, and temperature are taken from the 2-D model output, and additional excited-state reactions are added.…”
