             abstract = "We report the results of an ozone measurement campaign conducted 
                         at Natal, Brazil (5.9 degrees S, 35.2 degrees W)from March 25 to 
                         April 15, 1985. Seven profiles were obtained during this period, 
                         using ROCOZ-A and electrochemical concentration cell ozonesondes, 
                         standard U.S. meteorological radiosondes, and Super-Loki 
                         datasondes. Complete profiles of ozone, pressure, and temperature 
                         were obtained from the ground to 52 km, and all of the profiles 
                         correspond with site overpasses by ozone instruments on NASA and 
                         National Oceanic and Atmospheric Administration satellites. The 
                         profiles from this measurement series show reasonable agreement 
                         with established satellite climatologies. Stratospheric ozone 
                         variability was 2 or less during the 3 weeks of the measurement 
                         campaign, with stratospheric temperature and pressure 
                         variabilities half that amount. Low variability at a single 
                         location for this period implies comparable uniformity for ozone 
                         profiles over a large area around the measurement site. This 
                         condition at Natal removes the requirement of exact concurrence 
                         between satellite and local ozone measurements, allowing 
                         comparisons of larger sets of profiles and improving the precision 
                         of the intercomparisons. Regional ozone stability also allows an 
                         overall intercomparison of ozone measurements among the four 
                         satellites without the need for zonal mean averages. The auxiliary 
                         pressure and temperature profiles presented here allow the use of 
                         this data set as a transfer standard between satellite instruments 
                         with different fundamental ozone measurements. Finally, the low 
                         ozone variability in the stratosphere at Natal during this 
                         measurement series should provide an opportunity for high-quality 
                         intercomparisons of measured and modeled ozone concentrations in 
                         the equatorial stratosphere and lower mesosphere as well as a 
                         consistency check among satellite ozone measurementsm.",
