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. Since the late seventies, when Crutzen et al. (1979) first proposed that the emissions of trace gasesfrom biomass burning can make an important contribution to their budgets in the atmosphere, there has been an increase in the number of research activities in parts of the world with extensive biomass burning (Andreae, 1991). It is observed that biomass burning occurs mostly int he continental tropics coinciding with the local dry season (Crutzen et al., 1985). Trace gases such as carbon monoxide (CO), methane (CH_4)< nitrogen oxides (NO_x = NO + NO_2) and non-methane hydrocarbons (NMHCs) which are emitted from the burning fires play important roles in the production of ozone, thereby impacting the tropospheric photochemical oxidant cycle.
