Abstract: The aim of this work is to construct a model (mean) profile for ozone and water vapor in Southern hemisphere latitude using 14 years (1993-2006) of Halogen Occultation Experiment (HALOE) satellite data and about 10 years (1998-2007) of the Southern Hemisphere Additional OZonesondes (SHADOZ) balloon measurement data from Nairobi (1.3°S; 36.8°E), Malindi (3.0°S; 40.2°E) and Irene (25.9°S; 28.2°E). A comparison of Haloe mean profile has made between 0° to 10° Southern Hemisphere latitude with Nairobi and Malindi SHADOZ ozonesonde data, 20° to 30° with Irene SHADOZ measurement data respectively. A good agreement in terms of ozone and water vapour measurements has been found between SHADOZ ozonesonde and Haloe. The relative percentage of difference lies within 5 % for the height region from 4.5 km to 30 km altitude whereas, the comparison of mean water vapour show high uncertainty.
