Caption: Figure 6.
Cloud cover fraction above elevation 10° (CM10) measured by the CLASS site cameras from 2016 August to 2022 May. The nighttime data prior to 2017 January are discarded due to the low exposure time set for the cameras. Main: histogram of CM10 in local time and date. Top: the annual variation. The PWV measurements during the same time period are shown as shaded curves, with arbitrary scaling. The gray shades break when the APEX weather data are not available. Right: the season-averaged diurnal variation during Austral summer (December, January, February, in green) and Austral winter (June, July, August, in purple).
