abstract = "In the Amazon Basin, biogenic, biomass burning, and urban
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
CO and O3 aircraft measurements taken during the BARCA
(Balan{\c{c}}o Atmosf{\'e}rico Regional de Carbono na
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,
EDGAR4 urban emissions updated with vehicle emissions inventories
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
and regional distributions is evaluated.",
