Assessing the impact of clouds on ground-based UV–visible total column ozone measurements in the high Arctic [PDF]

Atmospheric Measurement Techniques, 2019
Zenith-Sky scattered light Differential Optical Absorption Spectroscopy (ZS-DOAS) has been used widely to retrieve total column ozone (TCO). ZS-DOAS measurements have the advantage of being less sensitive to clouds than direct-sun measurements.
