abstract = "Forests represent an important role in the control of atmospheric
emissions through carbon capture. However, in forest fires, the
carbon stored during photosynthesis is released into the
atmosphere. The carbon quantification, in forest burning, is
important for the development of measures for its control. The aim
of this study was to quantify CO2 and CO emissions of forest fires
in Western Amazonia. In this paper, results are described of
forest fire experiments conducted in Cruzeiro do Sul and Rio
Branco, state of Acre, and Candeias do Jamari, state of
Rond{\^o}nia, Brazil. These cities are located in the Western
portion of the Brazilian Amazon region. The biomass content per
hectare, in the virgin forest, was measured by indirect methods
using formulas with parameters of forest inventories in the
central hectare of the test site. The combustion completeness was
estimated by randomly selecting 10% of the total logs and twelve 2
× 2 m2 areas along three transects and examining their consumption
rates by the fire. The logs were used to determine the combustion
completeness of the larger materials (characteristic diameters
larger than 10 cm) and the 2 × 2 m2 areas to determine the
combustion completeness of small-size materials (those with
characteristic diameters lower than 10 cm) and the. The overall
biomass consumption by fire was estimated to be 40.0%, 41.2% and
26.2%, in Cruzeiro do Sul, Rio Branco and Candeias do Jamari,
respectively. Considering that the combustion gases of carbon in
open fires contain approximately 90.0% of CO2 and 10.0% of CO in
volumetric basis, the average emission rates of these gases by the
burning process, in the three sites, were estimated as 191 ± 46.7
t ha-1 and 13.5 ± 3.3 t ha-1, respectively.",
