Evidence for strong, widespread chlorine radical chemistry associated with pollution outflow from continental Asia

Abstract:
The chlorine radical is a potent atmospheric oxidant, capable of perturbing tropospheric oxidative
cycles normally controlled by the hydroxyl radical. Significantly faster reaction rates allow chlorine
radicals to expedite oxidation of hydrocarbons, including methane, and in polluted environments, to
enhance ozone production. Here we present evidence, from the CARIBIC airborne dataset, for extensive
chlorine radical chemistry associated with Asian pollution outflow, from airborne observations made
over the Malaysian Peninsula in winter. This region is known for pe ... mehr
