USING CATT-BRAMS FOR NUMERICAL SIMULATION OF THE TRANSPORT OF
POLLUTION EMITTED BY VEGETATION FIRES OVER EUROPE IN 2003
6th RAMS/BRAMS/OLAM International Users Workshop. 12- 14 May, Ubatuba, Brazil
Objective
The objective is to investigate the atmospheric transport of gases and particles emitted by biomass burning during the occurrence of heat wave that affected Europe on August 2003 (critical period occurred between 31th July and 03th of August). The simulations were implemented using the on-line 3-D transport model CATT-BRAMS (Coupled Aerosol and Tracer Transport model to the Brazilian developments on the Regional Atmospheric Modeling System) coupled to
an emission model.
