Ozone loss and chlorine activation in the Arctic winters 1991-2003 derived with the tracer-tracer correlations
International audience Chemical ozone loss in the Arctic stratosphere was investigated for the twelve years between 1991 and 2003 employing the ozone-tracer correlation method. For this method, the change in the relation between ozone and a long-lived tracer is considered for all twelve years over t...
