CHOCHO (glyoxal) is a good indicator for emissions of Volatile Organic Compounds (VOCs) as it is produced as a secondary product from their oxidation as well as directly emitted from combustion processes. Its short lifetime of a few hours leads to enhanced signals at proximity of its production sources. CHOCHO is also involved into the production of secondary organic aerosols (SOA), which affect both air quality and climate forcing.
