Abstract

Key Points:• Indianapolis CH 4 emissions are 49 ± 16 mol s -1 , with the South Side Landfill contributing 27 ± 10 mol s -1• Boundary layer entrainment must be corrected when using upwind flights to define CH 4 background concentrations• A mesoscale CH 4 model can filter complex background days, reducing emission variance by 25% in the case of Indianapolis
