Tropical fire emissions of methane represent a significant but highly uncertain source of the global methane budget (~5-15%) because of the variability of dry matter burned, the fuel type, and combustion phase. In this research we use satellite measurements of free-tropospheric CH4 and CO from the Aura Tropospheric Emission Spectrometer (TES), CO profiles from Terra MOPITT, and total column measurements of CH4 and CO2 from the TANSO GOSAT instrument to quantify fire emissions of methane from South America, Africa, and Indonesia for the 2009 to 2010 time period. Wetland fluxes of methane are a confounding factor when estimating fire emissions; we resolve how variations in wetland fluxes affect fire emission estimates using a combination of inundation area measurements and examination of wetland flux variability after the rainy season but before the dry season.
