To investigate the effects of decadal solar variability in ozone, data obtained from the Halogen Occultation Experiment (HALOE) onboard Upper Atmospheric Research Satellite (UARS) during the period 1992-2004 have been analysed using a multifunctional regression model. Solar effects on ozone are analysed over the 0-30° N and 0-30° S belts. The solar effect on ozone is found to be significant in most of the stratosphere (2 ± 1.1 to 4 ± 1.6%/100 sfu). It is negligible in the lower mesosphere whereas it is of the order of 5%/100 sfu in the upper mesosphere. These observed results are in reasonable agreement with model simulations. Results indicate a hemispheric symmetry in the tropics. Results obtained in the present study are also compared with the results obtained by other workers.
