Animations of CO2 concentration in the free troposphere, as simulated by NOAA's ESRL CarbonTracker.
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 movies are available in Quicktime and animated GIF format.
Quicktime files can be paused and played back with slider but animated GIF cannot.
Animated simulations based on data from the global CO2 collection network begun by Charles David Keeling in 1958 during the International Geophysical Year (IGY).
Animations show seasonal and regional variability of carbon dioxide emissions in recent years.
Passed initial science review - expert science review pending.
Tutorial provides more info, which may be of use to the instructor to look at prior to showing in class.
Some guiding questions to stimulate inquiry and discussion might include the following: What time of year and what region have the highest concentrations of tropospheric CO2?; What might be some of the contributing factors?; What role does weather play in the distributing and mixing of CO2 in the atmosphere?; Why does the northern hemisphere have more variability in concentrations of CO2 than the southern hemisphere?
