Children's Health Study (CHS) Sites: October 2003 Fire - 24-Hour Maximum PM10 Values

This page updated September 7, 2010.

Below is a data plot of the 24-hour maximum PM10 mass data from October 20 to November 1.
The dark blue line on the left is the data from Lake Arrowhead's Rim of the World High School. The elevated levels in the Lake Arrowhead data starting on October 21 reflects the onshore winds blowing the smoke from the beginnings of both the Padua fire and the Grand Prix fire into the Lake Arrowhead area.
Many of the fires around the Los Angeles Air Basin began or greatly expanded around October 25. The in-basin sites like Mira Loma, Riverside and Upland had the biggest peaks during October 25 and 26. Also notice the extremely high peak levels of PM10 mass during the period between October 25 and October 27 for all of the basin sites.
A cool weather front came in on October 28 and began to clear the air over the Los Angeles Basin. By October 30 the rain had cleared the air in almost all of the basin sites. Only Glendora had one last smoky day before the weather conditions completely cleared the air.
