We use atmospheric models to simulate the behaviour of the atmosphere enabling us to predict the composition of the atmosphere at a given point in space and time.
The behaviour of the atmosphere can broadly be defined by chemical processes (e.g chemical reactions) and physical processes (e.g. wind). We use models to predict the magnitude and spatial distribution of emissions of gases into the atmosphere
Find out about Eulerian models and how we use them.
Get a taste of Lagrangian modelling with examples of how we use this type of model to calculate emissions.
