Natchez Trace Parkway's air quality benefits from the 444-mile parkway's predominantly rural forested position through Mississippi, Alabama, and Tennessee, with the surrounding deciduous forest providing natural filtration along most of the corridor. Vehicle traffic on the Parkway contributes modest local sources, while the forested setting and the generally low traffic volume maintain good conditions for most of the parkway's length, with urban end sections near Nashville and Natchez tracking at moderate metropolitan levels.

Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
