Abstract: A critical analysis has been made on the variations of Antarctic, Arctic and tropical ozone and different solar parameters during the last solar cycle. It has been observed that yearly variations o f ozone concentrations at Halley Bay (76°S, 27°W), a British Antarctic survey station, at Sodankyla (67.4°N, 26.6°E), an Arctic survey station and at Ahmedabad (23°N, 72.6°E), an Indian survey station are identical to that of August, April and March concentrations, respectively. The yearly variations of solar flare numbers and solar uv-fluxes are identical to that of October values, but relative sunspot numbers and solar flare index are identical to that of April values. The correlation coefficients between ozone concentrations and different solar parameters are not so significant. It is also concluded that the intense yearly decrease of Antarctic and Arctic ozone concentrations from year to year during springtime is independent of solar parameters.
