                         emissions react photochemically to produce ozone, which is then 
                         transported by convection and regional circulations. As the Amazon 
                         basin becomes increasingly populated and developed for 
                         agriculture, the ability to predict regional ozone distributions 
                         will be critical to mitigating pollution that harms human health, 
                         agriculture, and natural ecosystems. However, major uncertainties 
                         remain in characterizing emissions, photochemical processes and 
                         pollutant transport in the Amazon basin. In this study, basin-wide

                         Amaz{\^o}nia) campaigns during the dry-to-wet (November and 
                         December 2008) and wet-to-dry (May 2009) transition seasons are 
                         used to evaluate the WRF-Chem and CCATT-BRAMS coupled chemistry 
                         and meteorology models, constrain emissions and analyze ozone 
                         budgets in the Amazon. The WRF-Chem (Weather Research and 
                         Forecasting with Chemistry) model developed at NOAA/ESRL was 
                         adapted in order to more realistically represent tropical 
                         meteorological and chemical processes. New WRF-Chem 
                         implementations include updated land cover and surface properties, 
                         soil moisture initialization from an off-line hydrological model,

                         for South American cities, and chemistry initial and boundary 
                         conditions from the MOCAGE global model. CCATT-BRAMS (Coupled 
                         Chemistry-Aerosol-Tracer Transport model coupled to the Brazilian 
                         developments on the Regional Atmospheric Modeling System) is 
                         currently in operational use for regional air quality forecasting 
                         at Brazil's National Institute for Space Research (INPE). 
                         Simulations were conducted with both models using RACM (Regional 
                         Atmospheric Chemistry Mechanism) and parameterizations for shallow 
                         and deep convection and 1D plume rise, with a 30/10km 2-way 
                         nested-grid configuration covering the Amazon Basin. The 
                         performance of the meteorological models was evaluated using flux 
                         tower and surface meteorological station data and the TRMM 
                         precipitation product. Simulated CO and O3 mixing ratios are 
                         compared with in-situ observations from the BARCA campaigns, and 
                         the model performance in reproducing both individual flight tracks
