Mean ozone and water vapor height profiles for southern hemisphere region using radiosonde/ozonesonde and haloe satelite data

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.
