Hemispheric Contrast of Inorganic Chlorine Partitioning in the Polar Lower Stratosphere during Ozone Recovery Period Observed from Space
The time evolution of two major chlorine reservoirs, HCl and ClONO2, in the polar lower stratosphere for both hemispheres in late spring and early summer was analyzed by utilizing satellite measurements. Analysis of the collocated ClONO2 observed with ILAS, and HCl observed with HALOE indicated that...
