Ozone loss and chlorine activation in the Arctic winters 1991?2003 derived with the TRAC method
International audience In this paper chemical ozone loss in the Arctic stratosphere was investigated for twelve years between 1991 and 2003. The accumulated local ozone loss and the column ozone loss were consistently derived mainly on the basis of HALOE observations. The ozone-tracer correlation (T...
