This is a graph of marine air temperature anomalies over the past 150 years. Five different marine air temperature anomaly datasets from different sources are compared on the one graph.
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
The ease of using this tool is really dependent upon students' understanding of an anomaly graph.
Clicking on the links to the data sources at the top of the graph will take you to the actual raw dataset.
Students can zoom and pan the data.
The data is represented on an anomaly graph. Educators may need to explain how an anomaly graph is constructed.
Educators need a clear understanding of and the ability to explain the statistical aspects of this data (e.g. interpolated vs. uninterpolated, anomolies, etc.)
Educators may want to explore other time series plots that are linked to.
Useful to highlight learner's opportunity to create different visualizations to really explore the data in meaningful ways.
The graph of marine air temperature anomalies over the past 150 years compares five different datasets from different sources. An explanation of each dataset is available. Links to derived anomaly data is available.
Comments from expert scientist: A strength of this activity is that the user can compare several long-term marine air temp. datasets at once, with the ability to zoom in and out of specific time periods for a close-up view. I rarely see these data presented in such a way online and think this is very useful for the audience.
Educators have the option of giving students the derived anomaly data and then have them plot and analyze the result.
