Each year, the Greater Los Angeles Basin is impacted by wildfire pollution from fires initiated primarily by the Santa Ana winds. In August 2009, the Los Angeles area was flooded with smoke from the 160,000 acre Station Fire. Atmospheric chemists from the Seinfeld group measured the wildfire pollution with particle chemistry and size resolving instrumentation from the top of the Keck Laboratory on the Caltech Campus. The results from these data are important for understanding local pollution impacts, but will also shed light on biomass burning pollution transformation in global climate models. The picture shown here is the Station Fire, taken from the roof of the Keck Laboratory.
