Comparison of the TOMS/SBUV tropospheric ozone residual (TOR) with the TOMS/SAGE TOR and low cloud frequencies

The 5-year (1985-1989) mean TOMS/SBUV tropospheric ozone residual (TOR) was compared with the 5-year mean TOMS/SAGE TOR. Many of the temporal and spatial features in the TOMS/SBUV TOR were similar to those found in the TOMS/SAGE TOR, suggesting a certain of consistency in the two data sets; however, significant differences were also noted. Some of these differences appear to be the result of spatial resolution differences between the TOMS/SBUV and TOMS/SAGE TOR data. Some, however, could not simply be explained by the spatial resolution differences. The comparisons between the 5-year (1985-1989) mean low-cloud frequency data with the TOMS/SBUV data showed that in some cases centers of persistent low clouds coincided with high ozone centers and in some case they did not
