Fig. 5: Regional comparison of August carbon monoxide (CO) emissions.
From: New seasonal pattern of pollution emerges from changing North American wildfires

Mean August CO emissions are shown in terragrams (Tg) for the two time periods (2002–2011, light colors, and 2012–2018, dark colors) for the three study regions: a PNW, b Central USA and c Northeast. We assess wildfire emissions from four inventories (Fire, red): QFED2.5, FINN1.5, GFED4.1s, and Zheng reanalysis, and two anthropogenic inventories (Anth, blue): CAMS-GLOB-ANT v3.1 and Zheng reanalysis. Note, Zheng reanalysis ends in 2017. Black circles represent regional August means for each year within the time periods.
