The error bars indicate SD of the emission and SOA production factors, and the error bands indicate the SD in the volatility fractions. (C) 300% for road asphalt) with greater SOA yields and sustained SOA production. The corresponding potential SOA that could be produced is also shown (hollow squares). —Khare et al.

The two combine in the atmosphere to make either nitric acid or peroxynitrous acid; the so-called branching ratio of these two chemicals is important in models of ozone production. This means less of the hydroxyl radical and nitrogen dioxide go away, leading to proportionately more ozone, mostly in polluted areas, Okumura said.

In California’s Los Angeles Basin, levels of volatile organic compounds (VOCs) pollutants have decreased by about 98% since the 1960s, even as area residents now burn approximately three times as much gasoline and diesel fuel. CO2 ratio for this flight track segment decreased from 24.5 ppbv/ppmv to 10.7 Source: Warneke et al.

Dust, ozone and carbon can accumulate in valleys and basins in California and other Western states. When you buy a product at Wal-Mart, it has to be manufactured somewhere. The product doesn’t contain the pollution, but creating it caused the pollution. —Steve Davis, UC Irvine Earth system scientist and co-author.
