Total ozone is closely connected with two crucial environmental problems: ozone depletion and global climate change. The Dobson spectrophotometer is the oldest measuring device (prototype) for total ozone observations in the atmosphere. The Dobson spectrophotometer No. 118 has been installed in Athens, Greece since 1989. We present a brief overview of the main activities of the instrument. According to the results of the intercomparison of the Athens Dobson spectrophotometer with World Standard Dobson Instruments, Dobson No. 118 is a reliable spectrophotometer and its measurements accurate and appropriate for further analysis. The comparison between Dobson measurements at Athens and all the available total ozone observations that have been performed using satellite-borne instrumentation revealed that it may be used as a ground-truth total ozone station for the validation of the satellite total ozone observations.
