Estimation and assimilation of aerosol and trace gases emissions in numerical models

Abstract

The environmental degradation is a topic discussed at all levels of scientific research. The changes of the natural elements by exploitative practices usually related to the use and management of vegetation causes changes in physical-chemical and biological interactions in components of the land surface and atmospheric composition. The main objective of this research project is to evaluate the use of fire radiative energy (FRE) to estimate and model in global scale the most important trace gases and aerosols emissions from biomass burning. Consequently, the emission inventories are going to be assimilated in the Brazilian Biomass Burning Emission Model (3BEM) model that provides emission maps for the Coupled Chemistry-Aerosol-Tracer Transport model coupled to Brazilian Regional Atmospheric Modeling System (CCATT-BRAMS) and for the new version of the global atmospheric model of the Center for Weather Forecasting and Climate Studies (CPTEC). Thus, fire radiative power (FRP) products from Moderate Resolution Imaging Spectroradiometer (MODIS), Geostationary Operational Environmental Satellite (GOES) and Spinning Enhanced Visible and Infrared Imager (SEVIRI) will be used to estimate aerosols and trace gases. In addition, we will analyze the environmental and climatic changes caused by the modification of biosphere-atmosphere system in the Amazon basin through the use of REGCM3 model. The simulations performance will be evaluated by comparisons of model results data collected in the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) Smoke, Aerosols, Clouds, rainfall, and Climate (SMOCC) and Radiation, Cloud, and Climate Interactions (RaCCI).
