Albedo is part of Earth’s energy budget. Albedo measures the percentage of incoming light that is reflected by a surface. This concept is used to understand how much energy the Earth gets from the Sun, and how much energy the Earth system radiates back to outer space.

The name of the parameter indicates all of the information about how the measurement was made. Refer to an overview.

This parameter is reported on a 72-Day cycle and is an average value for that 72-day period.
This parameter is a TOA measurement, meaning that it’s measured at the top of the atmosphere. For the purposes of Earth’s radiation budget, TOA is considered to be about 20 km above the surface of the Earth. Above that there is little interaction between the energy flux and the atmosphere.
Because this is an All-Sky parameter, it includes all types of conditions, including clear or cloudy skies that might occur during the measurement.
Albedo is the percentage of light that is reflected back out of the Earth system.
Overall, this parameter measures the amount of incoming light that is reflected from the top of the Earth’s atmosphere.
