Abstract

Mean global total ozone is estimated as the latitudinally weighted average of total ozone measured by the TOMS and OMI satellite mounted ozone measurement devices for the periods 1979-1992 and 2005-2015 respectively. The TOMS dataset shows an OLS depletion rate of 0.65 DU per year on average in mean monthly ozone from January 1979 to December 1992. The OMI dataset shows an OLS accretion rate of 0.5 DU per year on average in mean monthly ozone from January 2005 to December 2015. The conflicting and inconsequential OLS trends may be explained in terms of the random variability of nature and violations of OLS assumptions that can create the so called Hurst phenomenon. These findings are inconsistent with the Rowland-Molina theory of ozone destruction by anthropogenic chemical agents because the theory implies continued and dangerous depletion of total ozone on a global scale until the year 2040.
