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

This page updated September 7, 2010.

Below is a data plot of PM10 mass data for the Long Beach CHS site from October 20 to November 1.
The Long Beach area was filled with smoke almost constantly for four consecutive days in a row from October 25 to October 29. The fires in southern California started around October 25th. The cool weather front came in on October 28 and rain fell during the day of October 29. Extremely high levels of PM10 mass occurred during the period between October 25 and October 27 when compared to the "normal" summer pattern of seasonal PM10 mass during the preceding dates of October 20 to October 23. There is also a noticeable difference in ambient summer season levels of PM10 mass before the rain in the period from October 20 to October 25 and the lower ambient winter season levels after the rain began  falling on October 29.
