Ozone density profiles obtained through electrochemical concentration cell (ECC) sonde measurements at Natal were analyzed. Time variations, as expected, are small. Outstanding features of the data are tropospheric densities substantially higher than those measured at other stations, and also a total ozone content that is higher than the averages given by satellite measurements. Previously announced in STAR as A82-29798
In the present investigation, results obtained at three different locations are compared, taking into account the McDonald Observatory (latitude 30.7 deg N, longitude 101.0 deg W, altitude 2050 m), Mt. Haleakala (latitude 20.7 deg N, longitude 156.6 deg W, altitude 3050 m), and Cachoeira Paulista (latitude 22.7 deg S, longitude 45.0 deg W, altitude 500 m). The intercomparison of results from the three well-separated sites makes it possible to make evaluations of the local time, storm time, and latitude variation of the ring current precipitation.
