Biomass burning is widespread, especially in the tropics. It serves to clear land for shifting cultivation, to convert forests to agricultural and pastoral lands, and to remove dry vegetation in order to promote agricultural productivity and the growth of higher yield grasses. Furthermore, much agricultural waste and fuel wood is being combusted, particularly in developing countries. Biomass containing 2 to 5 petagrams of carbon is burned annually (1 petagram = 1015 grams), producing large… 
Biomass Burning: Local and Regional Redistribution
Tropical biomass biogeochemistry is one of the most poorly understood on the earth. The tropics account for about 60% of the global annual net primary productivity and this enormous productivity is
Impacts of biomass burning on tropospheric CO, NOx, and O3
This study utilizes the National Oceanic and Atmospheric Administration Geophysical Fluid Dynamics Laboratory three-dimensional global chemical transport model to quantify the impacts of biomass
Domestic Combustion of Biomass Fuels in Developing Countries: A Major Source of Atmospheric Pollutants
Biomass burning has important impacts on atmospheric chemistry and climate. Fires in tropical forests and savannas release large quantities of trace gases and particulate matter. Combustion of
Molecular nitrogen emissions from denitrification during biomass burning
THE burning of biomass (forest vegetation, savannah grass, firewood and agricultural wastes) due to human activities in the tropics is an important source of nitrogen compounds in the atmosphere1–4.
Impact of the Great China Fire of 1987 on the Tropospheric Chemistry of East Asia
There is a growing concern that biomass burning as a consequence of anthropogenic activities has significant impact on the atmospheric chemistry, climate and on the global biogeochemical cycles.
Biomass Burning and the Production of Greenhouse Gases. Chapter 9
Biomass burning is a source of greenhouse gases, carbon dioxide, methane, and nitrous oxide. In addition, biomass burning is a source of chemically active gases, including carbon monoxide, nonmethane
Composition of Smoke from North American Boreal Forest Fires
The release of gaseous and aerosol products into the atmosphere during controlled and naturally occurring vegetation fires is exerting a global influence on both atmospheric chemistry and climate

Biomass is any organic material, which can be used in its solid form or gasified for heating applications or electricity generation, or it can be converted into liquid or gaseous fuels. Wood is the
Moisture effects on carbon and nitrogen emission from burning of wildland biomass
Abstract. Carbon (C) and nitrogen (N) released from biomass burning have multiple effects on the Earth's biogeochemical cycle, climate change, and ecosystem. These effects depend on the relative
Impact of biomass burning on rainwater acidity and composition in Singapore
The Indonesian forest fires that took place from August through October 1997 released large amounts of gaseous and particulate pollutants into the atmosphere. The particulate emissions produced a


Importance of biomass burning in the atmospheric budgets of nitrogen-containing gases
BIOMASS burning is a primary source of many trace substances that are important in atmospheric chemistry1–6. More than 80% of the world's biomass burning takes place in the tropics3 as a result of
Tropospheric chemical composition measurements in Brazil during the dry season
Field measurement programs in Brazil during the dry seasons in August and September 1979 and 1980 have demonstrated the large importance of the continental tropics in global air chemistry. Many
Estimates of gross and net fluxes of carbon between the biosphere and the atmosphere from biomass burning
In order to estimate the production of charcoal and the atmospheric emissions of trace gases volatilized by burning we have estimated the global amounts of biomass which are affected by fires. We
Soot Carbon and Excess Fine Potassium: Long-Range Transport of Combustion-Derived Aerosols
During a cruise from Hamburg to Montevideo, aerosol samples representing air masses from Europe, the Sahara, tropical Africa, South America, and open oceanic regions were collected and the ratio of soot carbon to fine carbon suggests that most of the particulate organic carbon over the Atlantic is of continental origin.
The cycle of biogenic sulfur compounds over the Amazon Basin: 1. Dry season
We determined the concentrations of gaseous and participate sulfur species over the Amazon Basin during July/August 1985. The concentration of dimethylsulfide (DMS) in the mixed layer was near 10
Biomass burning in Amazonia: Seasonal effects on atmospheric O3 and CO
The practice of shifting agriculture and the need for the colonization of new land areas determine each year considerable amounts of biomass burnings in the Brazilian Amazon region. This paper
Simulation of the regional climatic impact of Amazon deforestation
THE Amazon basin contains about half of Earth's Tropical forest1. Population pressure and subsequent demands for crop production, timber and firewood have led to rapid deforestation. Quantitative
Convection links biomass burning to increased tropical ozone : however, models will tend to overpredict O3
Biomass burning throughout the inhabited portions of the tropics generates precursors which lead to significant local atmospheric ozone pollution. Several simulations show how this smog could be only
Deforestation alters denitrification in a lowland tropical rain forest
Nitrogen gas loss from terrestrial ecosystems is the most poorly quantified component of the global nitrogen cycle1–3. Particularly little is known about gas losses from tropical rain forests, which
Nitrogen Transformations Following Tropical Forest Felling and Burning on a Volcanic Soil
We measured nitrogen transformations and loss following forest clearing in a relatively fertile tropical forest site. Nitrogen mineralization, nitrification, and amounts of ammonium and nitrate
