4 sources for · 0 against

Multiple studies demonstrate that increasing cloud cover systematically attenuates solar radiation and decreases surface illuminance.

The analysis

The retrieved literature consistently supports the well-established physical principle that cloud cover reduces surface solar radiation and illuminance through scattering and absorption. Papers 2, 3, 9, and 11 all explicitly discuss how cloud parameters (such as cloud fraction and cloud optical depth) decrease surface-reaching shortwave radiation and solar irradiance.
