Stratospheric nitrogen dioxide in the Antarctic [PDF]

open access: yesInternational Journal of Remote Sensing, 2005
Several UV-Visible spectrometers have been developed at the ISAC-CNR Institute. Differential Optical Absorption Spectroscopy (DOAS) methodology is applied to their measurements to monitor the amount of stratospheric trace gases: mainly ozone (O3) and nitrogen dioxide (NO2) deeply involved in the ozone cycle.
