Smoke Emissions from Wildland Fires
Biomass burning is a major source of emissions to the atmosphere. Some of these emissions may change global climate. This paper uses combustion eff iciency as an independent variable for predicting emission factors for, among others, carbon monoxide, carbon dioxide, methane, and particulate matter. Other gases are correlated with the release of carbon monoxide. The release of nitrogen and sulfu...
متن کاملEmissions from Forest Fires Near Mexico City
The emissions of NOx (defined as NO (nitric oxide) + NO2 (nitrogen dioxide)) and hydrogen cyanide (HCN), per unit amount of fuel burned, from fires in the pine forests that dominate the mountains surrounding Mexico City (MC) are about 2 times higher than normally observed for forest burning. The ammonia (NH3) emissions are about average for forest burning. The upper limit for the mass ratio of ...
متن کاملGlobal burned area and biomass burning emissions from small fires
Global burned area and biomass burning emissions from small fires" (2012). NASA Publications. Paper 144. [1] In several biomes, including croplands, wooded savannas, and tropical forests, many small fires occur each year that are well below the detection limit of the current generation of global burned area products derived from moderate resolution surface reflectance imagery. Although these fi...
متن کاملEmissions from Coal Fires and Their Impact on the Environment
Self-ignited, naturally occurring coal fires and fires resulting from human activities persist for decades in underground coal mines, coal waste piles, and unmined coal beds. These uncontrolled coal fires occur in all coal-bearing parts of the world (Stracher, 2007) and pose multiple threats to the global environment because they emit greenhouse gases—carbon dioxide (CO2), and methane (CH4)—as ...
متن کاملUncertainty in estimating carbon emissions from boreal forest fires
[ I ] The uncertainty in carbon einissions fi-om fire was esti~nated for the boreal region of Alaska over the 50 years of recorded wildfire. Building on previous work where carbon emissions were estimated using a geographic infonnation systems-based model, the uncertainty attached to the different parameters of the basic equation was assessed and propagated through the equation using Monte Carl...
