Mapping the Distribution of Nitrogen Dioxide in the Mississippi Region

August 29th, 2019

What do the spatial patterns of the distribution of nitrogen dioxide reveal about human-environment relations? And how do pollution levels along the Mississippi compare globally?

Nitrogen dioxide is the product of numerous combustion processes initiated by humankind. Using satellite techniques, its associated trace gases can be mapped, allowing the sources of their emission—natural and anthropogenic—to be identified, quantified and spatially plotted. This project maps the way pockets of nitrogen dioxide have accumulated in the Mississippi region, comparing this activity with the average distribution found along the Nile and Yangtse.
