Frequently Asked Questions: (7) What is Particulate Dispersion Modeling?

The importance of the dispersion modeling, the effect of the long range transport of various pollutants along with their possible chemical transformation was briefly discussed earlier. Similar to the emissions inventory development, the dispersion modeling is also an intense exercise, which requires both computational power (nowadays, which is not a problem) and the data assimilation.

The modeling systems are plenty, with varying capacity and complexity. However, selection of the modeling system should be based on the objective of the program and institutional strength to absorb the analytical challenges.

See tools for air quality modeling and management.

The table below provides a general understanding of the types of the models available and the level of possible complexity with the handling of physical and chemical mechanisms.
