1. Introduction
California has a rich history of air quality studies conducted over more than 3
decades. The most recent and comprehensive air quality studies to date in northern
California are the Central California Ozone Study [1] (CCOS) and the California
Regional PM10/PM2.5 Air Quality Study (CRPAQS) that took place in the year
2000. Results of these air quality studies were used in developing State Implemen-
tation Plans (SIPs) for the northern California region. Recent comprehensive air
quality studies in the southern California region are the Southern California Ozone
Study (SCOS) of 1997, Multiple Air Toxics Exposure Study II (MATES-II) during
1998-1999, and MATES-III [2] during 2004-2006. Results of these studies were
used in developing SIPs for the southern California region.
Of the several small-scale air quality studies conducted in California since 2000,
the 2008 California portion of the A rctic R esearch of the C omposition of the
T roposphere from A ircraft and S atellites [3] (ARCTAS-CARB 2008) is particularly
significant. Prior to the ARCTAS deployment in Canada, NASA conducted a
series of flights in collaboration with scientists from the California Air Resources
