Rapid motion of the 1989 Arctic ozone crater as viewed with TOMS data
The data from the NIMBUS-7 TOMS instrument were used to study the Arctic ozone layer in late winter and spring, 1989. This paper presents an analysis of TOMS total ozone values, to produce a picture of the morphology of the Arctic stratospheric ozone crater in winter–spring 1989. The Arctic crater f...
