Photodissociation of particulate nitrate as a source of daytime tropospheric Cl2

This study unravels an important daytime Cl2 source in the extra-polar atmosphere and shows that photolysis of particle nitrate at high acidity produced unprecedented levels of Cl2, boosting the oxidative power and air pollutants like O3.
