Resumo | Wildfire emissions greatly deteriorate regional air quality and thus threaten human health. Biomass burning in the Amazon has substantial influence on the surrounding regions where pollution worsens during the dry season (Jul to Nov). Past research has shown that wildfire occurrence in Amazon is statistically related to interannual climate variability (e.g., ENSO) and drought events, whereas long-term changes in land use (e.g., deforestation) also greatly modulate fire activities and emissions. Here we use the Global Fire Emission Database Version 4 (GFED4) and a new emission inventory to drive a global 3-D atmospheric chemical transport model GEOS-Chem High Performance (GCHP) to estimate the impacts of deforestation, land degradation, and ENSO on fire emissions and regional air quality with a resolution of ~50 km in the Amazon. GFED4 is a global fire emission inventory that is widely used in past research while the new emission inventory is developed specifically for the Amazon region with regional biomass map incorporated. The new emission inventory distinguishes the emission from dry biomass burned from different types of fires (e.g., from deforestation vs. land degradation fires) and provides more accurate mortality and fuel load factors. We find that fires alone enhance the concentrations of fine particulate matter (PM2.5), carbon monoxide and ozone by 8.9 μg m-3, 0.21 ppm and 19 ppb, respectively, in the 2016 dry season (Jul-Nov). With the new emission inventory, we discover that deforestation has a greater contribution to air pollution in the southeastern parts of rainforest, whereas degradation has a greater contribution in the savanna regions. Apart from the fire types, we compare the regional pollutant average with GFED4 in dry season between El Niño, La Niña, and normal years. PM2.5, carbon monoxide and ozone are reduced by 0.8%, 10% and 7%, respectively, during La Niña dry season than that in El Niño period. Our study shows the significance of climate variabilities in shaping the air quality in Amazon region, and it is important to control not only deforestation fires but also degradation fires to improve regional air quality. |
