Observation of trace gases and carbon dioxide
Some gases in our atmosphere appear only close to their sources. Scents from trees have to be observed in the forest. Others like carbon dioxide spread nearly homogeneously round the globe and can be observed at many places. One measurement station is Mace Head. What do scientists do there?
Plant life as part of an atmospheric surrounding
Plant life is influenced by the atmospheric composition, the atmospheric composition is determined by plant life. Carbon dioxide needed in photosynthesis is a prominent example. What are the interactions?
Do you know where the greenhouse gas carbon dioxide in our atmosphere comes from and where it goes? Think about the role of plants and how to measure their influence.
