Trends in Atmospheric Nitrous Oxide

Ask a Question

  • How has the amount of nitrous oxide in the atmosphere changed over the past 20 years? This site allows you to interact with graphs and datasets to answer this question. 
  • Students will be able to see graphs depicting global average nitrous oxide amounts in the atmosphere and read text describing the data and how it was gathered. 

Teaching Tips


  • The graphs are simple and easy to read.

Additional Prerequisites

  • Teachers may want to provide some background about nitrous oxide's relationship to climate change.
  • Teachers should clarify the units mole fraction and parts per billion if students are unfamiliar.
  • If the technical reading is distracting, there are PDFs of the graphs and data that teachers can use instead.
  • The data is also downloadable in CSV files.


Scientist Notes
Datasets have good quality. There is no contradiction in the resource. This resource is recommended.
