Using data from the Global Ozone Monitoring
Experiment (GOME) ozone profiles and tropospheric ozone retrieval algorithms
were developed in order to accurately retrieve tropospheric ozone from
the total column ozone retrievals from GOME [Liu et al., 2005]. This
paper presents the first directly retrieved global distribution of total
column ozone using the same methods described in the above reference. These
retrievals are validated using the GEOS-CHEM chemical transport model.
Figure 6. Comparison of seasonal
average GOME and GEOS-CHEM (convolved with GOME averaging kernels)
tropospheric column ozone from December 1996 to November 1997.
Overall, the global GOME tropospheric
column ozone agrees well with the global GEOS-CHEM predictions. It
can be seen there is better agreement in the Southern Hemisphere compared
to the Northern Hemisphere.
