Children's Health Study (CHS) Sites: October 2003 Fire - Glendora

This page updated September 7, 2010.

This is a data plot of PM10 mass data for the Glendora CHS site from October 20 to November 1.
Increasingly high peak levels of PM10 mass occurred during the fire impacted period between October 25 and October 30 compared to the relatively lower "normal" peaks of the seasonal PM10 mass during the preceding dates of October 20 to October 23. The pre-fire data from this site shows clearly the diurnal or daily pollution cycles in this area. There is a morning peak from the commute traffic and then a smaller peak in the evening followed by relatively low levels overnight. The fires near this area started around October 25. Notice how the valleys in the data drop to lower levels when the cool weather front came in on the evening of October 29. The peak on October 30 is from transport of the last remnants of the fire's smoke being blown through the L.A. area by the onshore / offshore winds.
