Abstract

The burning of biomass emits a large quantity of gases and aerosol particles into the atmosphere. The particles interact with solar radiation, spreading out and absorbing, in such a way as to diminish the total quantity available on the surface and increasing the diffuse fraction. Such alterations in the profile of radiation affect the balance of radiation and the turbulent fluxes of sensible and latent heat and can affect photosynthesis. The principal objective of this research project is to continue with the study of the effect of aerosol particles emitted by burning in Amazonia on the photosynthesis of a primary tropical forest. It is also intended to evaluate whether the high concentrations of ozone, another subproduct of the fires, affect the photosynthesis process. (AU)
