             abstract = "A new 6 year data set of total column ozone is described at a 
                         southern tropical station, Natal (6 S, 35 W), which operates 
                         Dobson and Brewer spectrophotometers, and these are compared with 
                         the Total Ozone Mapping Spectrometer, Toms. In terms of the 
                         difference parameters, for the entire period, 100* (Brw-Dob)/Brw 
                         and 100*(Brw-Tms)/Brw monthly means are 0.2+/-1.2 and 0.0+/-2.1. 
                         Separating the data set in two periods, from 1997 to 2001, and 
                         from 2001 onwards, a significant change in the difference 
                         parameters is obtained for the Toms series. The difference between 
                         the two periods is then: -0.1+/-2.9 and -0.1+/-2.5%, for the 
                         Dobson series; and -1.0+/-2.9 and 1.9+/-3.0%, for the Toms series, 
                         respectively, thus showing a larger variability in the second part 
                         of the period.",
