Atmospheric Modelling

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

Models can be split into two types depending on how dynamics are dealt with, Lagrangian and Eulerian models.

Eulerian Modelling

Find out about Eulerian models and how we use them.

Lagrangian Modelling

Get a taste of Lagrangian modelling with examples of how we use this type of model to calculate emissions.
