Abstract

It is intended, using experimental measurements and numerical calculations using radioactive transfer codes, to quantify the effect of aerosol particles presente in the Amazon region of the solar irradiances observed on the surface and the top of the atmosphere. Particular emphasis will be given to the aerosol particles deriving from the burning of biomass. In cooperation with researchers from the Nasa Goddard Space Flight Center, experimental measurements will be evaluated obtained with a network of automatic spectral radiometers installed in the region and with the Modis sensor on board the Terra and Aqua satellites. A study of the effect of the layer of aerosol particles from the burning on the vegetation of the region will also be carried out, evaluating the consequence of the disturbance in the balance of photosynthetically active radiation on the surface on the photosynthesis, using a radioactive transfer code linked to a vegetation model.
