Title: Decadal solar signal in ozone and temperature through the mesosphere of Northern tropics

Abstract: Abstract: To investigate the effects of decadal solar variability on ozone and temperature in the mesosphere of the Northern tropics, data obtained from the Halogen Occultation Experiment (HALOE) aboard Upper Atmospheric Research Satellite (UARS) during the period 1992–2005 are analyzed using a multifunctional regression model. The inferred annual-mean solar signal in ozone is found to be insignificant in the lower mesosphere whereas it is of the order of 5%/100sfu in the upper mesosphere. Seasonal variation of ozone response to solar variability indicates a strong positive response (22–30%/100sfu) during summer and autumn between 5E-3 and 0.01mb pressure levels (∼80–85km). The annual mean temperature response is found to be of the order of 0.5–1K/100sfu. Significant positive temperature response is observed during winter and autumn in the lower mesosphere and during summer and spring in the upper mesosphere. Results obtained in the present study are also compared with the results obtained by other workers. [Copyright &y& Elsevier]
