Abstract
Based in the classical Gaussian model, a multi-puff approach was applied to
simulate Shenyang's air quality and evaluate the results by comparison with the
air quality measured data. Data assimilation was also used to improve modeling
results, based on the data from air quality monitoring stations in Shenyang. The
use of modeling results and measured data were obtained by optimal
interpolation, which can provide a linear estimator minimizing the covariance
error of analytic results based on correlation functions. It showed that the multi-
puff approach could be used to simulate the transport and dispersion of no
