Big brother in space - satellites watch the atmosphere

Nowadays, observation of the ozone hole could hardly be imagined without satellites. The research article describes how a new instrument gets into space (2002) and what it is able to do there.
 
context 

Light, absorption and matter

Visible light is part of the electromagnetic spectrum. We introduce 'invisible' light and explain how matter obstructing light causes changes in this spectrum.
