Air quality refers to the chemical composition of trace constituents close to the surface of the earth, which impact on humans. It is a global issue.

In situ measurements are ones that are obtained through direct contact with the respective subject.

Monitoring methods can range from on the ground to planes, towers, spacecraft, or vehicles.

This topic looks at street level monitoring. Many urban areas around the world have local street level air quality monitoring.

In this video Dr David Green goes into more detail about the street level sensors in London, and how they are used to monitor PM10 and PM2.5.

Satellites can measure lots of different sources of atmospheric pollution, such as Nitrogen Dioxide, Ozone, Carbon Monoxide and Particulate Matter.

In this video Johannes Flemming looks at a model showing Nitrogen Oxides produced from Lightning.

In order to manage the Earth’s resources and control atmospheric pollution from the local to the global scale, international agreements occur.

This topic looks at near real-time applications which can be used by the public to monitor air pollution around them.

This topic looks at citizen science, which involves members of the general public collaborating with scientists on a project.
