Cloud albedo

Cloud albedo is a measure of the reflectivity of a cloud - higher values mean that the cloud is blocking more solar radiation.

Cloud albedo varies from less than 10% to more than 90% of the incoming solar radiation and depends on drop sizes, liquid water content, water vapor content, thickness of the cloud, and the sun's zenith angle[?]. The smaller the drops and the greater the liquid water content, the greater the cloud albedo, if all other factors are the same.
