                         basis. In order to remove tidal effects only profiles obtained 
                         from 18:30 LT to 23:30 LT were considered in this analysis. We 
                         used these nightly profiles to determine the monthly temperature 
                         profiles from April 1993 to April 2014. The mean temperature

                         obtained and do not differ too much from the previous climatology
