INSUFFICIENT LEANING

Is it true that cloud cover reduces solar radiation intensity?
Unclear. Several peer-reviewed and reference items indicate that cloud cover generally weakens solar radiation reaching the surface, though one study notes intensification under partly cloudy convective conditions. All placed items are partial: single-site, single-wavelength, or modeling contexts rather than a general statement.
