Increased ultraviolet radiation in New Zealand (45°S) relative to Germany (48°N)

摘要: RECENT analyses of global ozone measurements have confirmed that reductions are not confined to the Antarctic, but now extend mid-latitudes in both hemispheres1,2. Ozone lead increases biologically damaging ultraviolet radiation3, and such been observed Antarctica1,4 Australia5. Little is known, however, about hemispheric differences intensities. Here we use a combination spectral made Germany New Zealand with same spectroradiometer, together model calculations, show summer 1990–1991 weighted irradiances were nearly factor two greater than those at similar northern latitudes Germany. These larger expected3,6, due mainly decreased stratospheric over increased levels tropospheric
