Then, by including additional vertical mixing of O 3 into the troposphere above the fires, and using a low NO x /CO emission ratio for boreal fires, O 3 concentrations in the simulated plumes are reduced closer to the aircraft measurements, with NO 2 closer to SCIAMACHY satellite instrument data, although too little PAN is produced. In the p-TOMCAT simulations the fire emissions lead to increased O 3 in the troposphere over much of North America, the north Atlantic and western Europe from photochemical production and transport. The increased O 3 over the northern hemisphere reaches a peak in the range 2.0 to 6.2 Tg. 3
