Hundreds of wildfires in Northern California were sparked by lightning during the summer of
2008, resulting in downwind smoke for the months of June and July. Comparisons are
reported for aerosol optics measurements in Reno, Nevada made during the very smoky
month of July and the relatively clean month of August. Photoacoustic instruments equipped
with integrating nephelometers were used to measure aerosol light scattering and
absorption coefficients at wavelengths of 405 nm and 870 nm, revealing a strong variation of …
