Las Delicias in Chihuahua reflects the flat Chihuahuan Desert agricultural plain position, with vehicle traffic on surrounding roads and agricultural operations contributing very modest local sources. Windblown Chihuahuan Desert dust contributes elevated PM10 during dry wind events, while the flat semi-arid terrain allows reasonable dispersal and the area generally maintains moderate to good northern Mexican Chihuahuan Desert agricultural readings throughout most of the year.
