Sixteen Years of Measurements of Ozone over Athens, Greece with a Brewer Spectrophotometer
Sixteen years (July 2003–July 2019) of ground-based measurements of total ozone in the urban environment of Athens, Greece, are analyzed in this work. Measurements were acquired with a single Brewer monochromator operating on the roof of the Biomedical Research Foundation of the Academy of Athens si...
