Surface ozone has been measured at Tranquabar (11°N, 79°9'E), a tropical rural site on the east coast of south India, during the years 1996 to 2004. The sunspot data were collected from Udaipur solar observatory during the same period. The relationship between annual mean smoothed sunspot number and annual mean surface ozone levels are studied by Pearson product moment correlation coefficient and that is found to be a high value 0.94. High positive rank correlation coefficients 0.76 and 0.62 obtained for the years 2000 and 2002 indicates the influence of higher solar activity over the surface ozone levels.

Abstract


Surface ozone has been measured at Tranquabar (11°N, 79°9'E), a tropical rural site on the east coast of south India, during the years 1996 to 2004. The sunspot data were collected from Udaipur solar observatory during the same period. The relationship between annual mean smoothed sunspot number and annual mean surface ozone levels are studied by Pearson product moment correlation coefficient and that is found to be a high value 0.94. High positive rank correlation coefficients 0.76 and 0.62 obtained for the years 2000 and 2002 indicates the influence of higher solar activity over the surface ozone levels.
