Carbon dioxide concentration in the atmosphere is affected, among other things, by processes involving forests including fires, deforestation and plant respiration. Evaluate a Landsat image to determine the rate of carbon dioxide sequestration in a particular area.
Explore using units in calculations with the Leaf Area Index (LAI). LAI is a ratio that describes the number of square meters of leaves per square meter of available land surface. Because of the units in the ratio, it is dimensionless
