Sample of One Day of Particulate Monitoring

[This slide illustrates one full day in Los Altos, CA. Across the bottom of the slide are the times of the day in military time. That way we can compare morning rush hour with the evening burning of wood. The air deteriorates at night when there is no traffic or industry. This was a Thursday night. Residential wood smoke is a dangerous form of air pollution which is not related to automobiles or industry; in the words of the comic strip character "We have met the enemy and they are us!" ]
