Study: Urban grime releases NOx when exposed to sunlight

Green Car Congress

When in the air, these compounds may combine with volatile organic compounds to produce ozone, the main component of smog. In a subsequent laboratory comparison, they found that nitrate disappeared from grime 10,000 times faster than from a water-based solution when both were exposed to artificial sunlight. —James Donaldson.

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

Despite their limitations, GWPs are widely used for comparison among long-lived gases, forming the basis for worldwide political agreements on climate and carbon trading. And hydroxyls drive long chains of reactions involving other common gases, including ozone. Similar reactions influence the creation of nitrate aerosols.
