Soledad de Graciano Sánchez's air quality reflects the flat San Luis Potosí plateau's suburban corridor adjacent to the state capital, with vehicle traffic on surrounding roads and the manufacturing, logistics, and residential character contributing local sources. The elevated plateau position aids dispersal on most days, while winter inversions create seasonal challenges and the manufacturing industrial character generally maintains moderate San Luis Potosí metropolitan eastern suburban readings throughout most of the year.
