High resolution satellite records of active fire and burned area extend now for more than a decade, allowing for improved estimates of fire emissions and a better understanding of fire-mediated feedbacks involving ecosystems, climate, and human activity. Here I describe a systematic framework for estimating global burned area and fire emissions (the Global Fire Emissions Database (GFED)) that uses MODerate Resolution Imaging Spectroradiometer observations from Terra and Aqua along with other satellite data streams as inputs to a biogeochemical model. I then use the GFED time series, with chemical transport and climate models, to assess fire effects on greenhouse gases and the transport of reactive nitrogen across biomes.
