Regional Focus


Global Atmospheric Nitrous Oxide Concentration

Ask a Question

  • This interactive chart allows students to explore the global atmospheric concentration of nitrous oxide (N2O) over time.
  • The chart can be customized to show a specific date range (starting in 1750) and can be downloaded.
Teaching Tips


  • Students can click the "play" arrow below the chart or table to see how the data has changed over time.
  • The resource uses data published by the European Environment Agency (EEA) from the Advanced Global Atmospheric Gases Experiment (AGAGE).

Additional Prerequisites

  • Students should know how to read a line graph.


  • This resource could be useful in a discussion about sustainability, the ozone layer, and the impacts of industrial farming.
  • Cross-curricular connections could be made with math classes when working with data and graphs.
  • Other resources related to this topic include this graph and table on nitrous oxide emissions by sector and this map of nitrous oxide emissions
  • Students could research the following questions:
    • How potent is nitrous oxide as a greenhouse gas?
    • How much nitrous oxide is released from fertilizer and livestock waste lagoons?
    • How does fertilizer use contribute to eutrophication and dead zones?
    • How potent is nitrous oxide as an ozone-damaging gas?
Scientist Notes

This resource depicts time series data on the average atmospheric concentration of N2O. Datasets acquired from EEA are accurate and the resource is recommended for teaching.
