The Albedo is the ratio between the radiant exitance and the irradiance at surface level over the shortwave spectral domain (broadband). The value range of albedo is 0 - 1. Albedo is derived from the SR (Surface Reflectance) product. Albedo is an Essential Climate Variable (ECV) as recognized by the Global Climate Observing System (WMO 2011).
Upcoming information about the Albedo product will be accessible soon.
