Cloud albedo

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

Cloud albedo varies from less than 10% to more than 90% and depends on drop sizes, liquid water or ice 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.
