Remote sensing of biomass burning associated with deforestation

A method based on remote sensing of one emitted product - particulates is developed for the global assessment of trace gases and particulates emission from tropical biomass burning. According to the method, the detected mass of emitted particulates is converted into a mass of emitted trace gases using published relations between the emitted particulates and trace gases for the flaming and smoldering phases. Through an analysis of the 1987 burning season in Brazil during the three months of the dry season, it is shown that there are up to 8000 fires a day each contributing 4500 tons of CO(2), 750 tons of CO, and 26 tons of CH(4) to the atmosphere. A comparison to the estimates of global emissions is also presented.
