Short summary
This study used new TROPOMI measurements of NO2 and CO to characterize regional biomass burning characteristics and efficiency. We found that the NO2 / CO emission ratio was consistent with recent studies over temperate forest fires but slightly lower in savanna vegetation fires. Our results can help identify the relative contribution of smoldering and flaming activities as well as their impacts on the regional atmospheric composition and air quality.
