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.
