Global distribution of oxygentaed organic species in the ...

Most oxygenated organics impact atmospheric photochemistry by providing free radicals and sequestering NOx from the system generally in the form of PAN1. Acetone and acetaldehyde are particular examples of this. Except for the alcohols, the oxygenates discussed here photolyze at tropospheric wavelengths and are a direct source of free radicals. ................
