Here is a graph showing how the controlled burn by Montana de Oro affected local air. It displays measurements of a size of particulate matter called PM-10. Note the huge spike at 1400 hours (2 p.m.) for Arroyo Grande and nearby Nipomo. There was another spike further south an hour later when the main cloud invaded Santa Maria.
