Lumped profiles for 3 temperatures (−18, −7 and 24 °C) into chemistry mechanisms. Calculated mass-based scaling factors and temperature-dependent parameterizations. Mechanisms considered: CB05, four variants for SAPRC and RACM2. SAPRC, RACM2 trends qualitatively similar to raw profile, CB05 markedly different. Parameterizations differ across mechanisms for similar model species.
