Isure looks like it might have something to do with higher elevation and less rain fall. I can see in the Sacramento valley having higher levels due to agriculture. It also appears that cities produce higher levels as well. Natural NO2 is described below.
Dinitrogen or simply nitrogen gas, N2, is the most abundant gas in the atmosphere at 78.1% by volume. Nitrogen is a colorless gas at room temperature. While N2 is generally quite inert chemically, it is utilized by nitrogen-fixing organisms and this is the primary natural nitrogen input to terrestrial and marine ecosystems. Biological nitrogen fixation refers to the natural process that is performed by a variety of bacteria and algae, both symbiotic and free living.
The natural flux of N2 from the atmosphere to oceans and terrestrial ecosystems is balanced by a nearly equal source of N2 to the atmosphere in a process called denitrification.
