Ground based NO2 and O3 measurements by visible spectrometer at Syowa Base (69 deg S), Antarctica
The column amounts of NO2 and ozone have been measured using visible spectroscopy at Syowa Base (69 deg S) since March 1990. Ozone was also measured at the same location with a Dobson spectrometer as well as ozonesondes being flown regularly. The characteristic features of the seasonal and diurnal v...
