Zusammenfassung |
Coupled Chemistry Aerosol-Tracer Transport model to the Brazilian
developments on the Regional Atmospheric Modeling System (CCATT-BRAMS,
version 4.5) is an on-line regional chemical transport model designed for
local and regional studies of atmospheric chemistry from the surface to the
lower stratosphere suitable both for operational and research purposes. It
includes gaseous/aqueous chemistry, photochemistry, scavenging and dry
deposition. The CCATT-BRAMS model takes advantage of BRAMS-specific
development for the tropics/subtropics as well as the recent availability of
preprocessing tools for chemical mechanisms and fast codes for photolysis
rates. BRAMS includes state-of-the-art physical parameterizations and dynamic
formulations to simulate atmospheric circulations down to the meter. This
on-line coupling of meteorology and chemistry allows the system to be used
for simultaneous weather and chemical composition forecasts as well as
potential feedback between the two. The entire system is made of three
preprocessing software tools for user-defined chemical mechanisms, aerosol
and trace gas emissions fields and the interpolation of initial and boundary
conditions for meteorology and chemistry. In this paper, the model
description is provided along with the evaluations performed by using
observational data obtained from ground-based stations, instruments aboard
aircrafts and retrieval from space remote sensing. The evaluation accounts
for model applications at different scales from megacities and the Amazon
Basin up to the intercontinental region of the Southern Hemisphere. |
