Atotonilco el Alto's air quality reflects the flat Jalisco Altos plateau at 1,609 metres, with vehicle traffic on surrounding roads and the tequila agave, livestock, and agricultural corridor contributing local sources. The elevated plateau position aids dispersal on most days, while winter inversions create modest seasonal challenges and the agave processing operations' distinctive organic aerosols represent Atotonilco's most locally notable air quality contribution throughout most of the year.
