Abstract

In this project it is proposed to use numerical models in the modeling of the transformation and transport of natural aerosol particles and particles from biomass burnings in the Amazon region.We will develop interfaces that will permit the coupled use of the Regional Atmospheric System (RAMS), the physics aerosol model Community Aerosol & Radiation Model for Atmospheres (CARMA), and a model of emitting sources of aerosols from biomass burnings. The system composed of these three models will enable the undertaking of numerical simulations of the spatial and temporal distribution of the aerosol particles, as well as of their optical properties. Special attention will be dedicated to the interaction of these particles with solar radiation and with the microphysics of clouds and to their potential climatic effects. We will emphasize the use of products of remote sensing in the initialization and validation of the results. (AU)
