Impact of the overlapping O2 Schumann-Runge and Herzberg continua with Schumann-Runge bands on photolysis rate coefficients: comparing the Koppers & Murtagh parameterization with line-by-line cross section

Key Points

• Photolysis rate coefficients are significantly influenced by overlapping continua in the Schumann-Runge bands.
• The Koppers and Murtagh parameterization shows up to 20% variation compared to line-by-line cross section measurements.
• Analysis utilized line-by-line cross section for precise evaluation of photolysis rates across different scenarios.
• Recommendations for improved parameterization methods could enhance photochemical modeling accuracy.
