n this paper, we consider dynamic Bayesian models for four different
pollutants: nitric oxide (NO), carbon monoxide (CO), sulphur dioxide (SO
2
)
and non-methane hydrocarbon (NCH
4
) recorded daily in six different stations
in Kuwait from 1999 to 2002. The structures of the models depend on time,
space and pollutants. The approach strives to incorporate the uncertainty of
the covariance structure into simulated models and final inference; therefore,
hierarchical Bayesian model is applied. Association between level of pollutants
and different meteorological variables, such as wind speed, wind directions,
temperature and humidity are considered. The models will decompose into two
main components: a deterministic part to represent the observed components
term and a stochastic term to represent the unobservable components. Our
analysis will start with basic model and gradually increase its complexity. At
each stage the efficiency of the model will be measured. The resulting models
subsequently are tested by comparing the output terms and by comparing and
the predictions with the real observations.
