Atmospheric Dispersion Models
Overview of models
There are atmospheric dispersion models of many different types - all sorts of simple models as well as complex models. In a given situation it may be justified to use a simple model - it all depends on the conditions. A model should be fit for the purpose for which it is applied.
There are numerous ways to classify models (e.g., they can be classified according to the policy issue they address). Examples: industrial pollution, urban air quality, nuclear emergencies, chemical emergencies, climate change, etc.
Another option is to to classify models according to model concept. Examples: Gaussian models, Eulerian models, Lagrangian models, receptor models, etc.
There are several other schemes for the classification of dispersion models.
The Model Documentation System, managed by the European Topic Centre on Air and Climate Change (which is a Centre in the framework of European Environment Agency), is a searchable data base of dispersion models, with a structured description of each model. In the data base, models are classified according to several schemes. The Model Documentation System is a good place to start if you look for information about a model with certain capabilities, or if you look for a description of one or several models.
The Model Documentation System is not limited to European models, although at present European models dominate the data base.
Links to compilations of models
This section provides links to compilation pages concerning models - both on this wiki and external pages. Feel free to add links...
- Model Documentation System - Very central. Described above, maintained by the European Topic Centre on Air and Climate Change
- COST 728/732 Model Inventory. An inventory originated in action COST 728, Enhancing mesoscale meteorological modelling capabilities for air pollution and dispersion applications, but covers also microscale models. Some overlap to the Model Documentation System.

- Compilation of British and Australian models - Article within the present wiki with further links
- Individual models - listing
- User communities.
- International networks on atmospheric pollution
- Dispersion model category - Most pages on the Atmospheric Dispersion Wiki are classified according to category, one of which is the Dispersion model category. The link yields an index of all pages within this category. (There is a similar link at the bottom of almost every page).
You are welcome to contribute with links and with Wiki pages commenting models and types of models. How?.
