Near-real time plots from Syowa

Total ozone is measured at the Japanese GAW station Syowa (69.006°S, 39.577°E) with a Dobson spectrophotometer. These measurements have been carried out since 1961. Measurements started up on 21 August after the winter. The total ozone value measured with the Dobson spectrophotometer on that day showed 211 DU. Ozone profiles are measured at Syowa with ozonesondes.
