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.

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.


Test your knowledge of light, satellites and ozone in the atmosphere. Link related terms and fill in text with gaps and graphics.


We observe our planet with modern measurement techniques. You will find further sources of information about such technologies, satellite measurements and the relation between light, matter, atmosphere and climate in the link list.

Information for teachers

Solutions to the worksheets, material for downloading, ideas for integration to curriculum and for the extension of the topic are found in this section.
