Autumn Leaves for US Air Quality Gradebook - Maps

 

Hyperlinks below access maps of air quality for each state.  The maps grade air quality in counties from A to F, with A being the best/cleanest in the US, and F being the worst/dirtiest.  For grading details, see the emission gradesheets and ambient gradesheets.

 

Because air masses flow readily across county lines, the maps restrict grade changes across county boundaries to one level, as C to D, and not C to F.  Therefore, a county’s neighbors may lower its grade from what appears on the

gradesheets.  The maps consider a county in the context of its neighboring counties, whereas the gradesheets consider counties individually.1  Bordering counties may be in adjacent states.2

 

Click a state on the map or list to bring up its air quality map.  The first map in the list is an overview of the entire United States.  After viewing a map, click the browser’s back button/arrow to return to this index page.3

1 Gradesheet D’s and F’s remain.  Grades A, B, and C go to D if bordering counties are F.  Then, A and B go to C if bordering counties are D.  Then, grades A go to B if bordering counties are C.

2 The maps assume bordering areas in Mexico and Canada do not modify levels in neighboring US counties.
