Earth albedo is the sunlight reflected off the Earth's surface. The Earth albedo induces power in solar cells on spacecrafts just like direct sunlight. The Earth Albedo Toolbox may be used to calculate the amount of Earth albedo arriving at an object in space, maintaining information of direction of the Earth albedo, useful for objects in low Earth-orbit. The Earth Abledo model is useful for investigating excess energy produces by solar panels, and for improving vector observations by Sun sensors. A Simulink interface is provided with toolbox.

Where is it possible to get the reflectance data needed for this? If someone has it could they please send it to me? I need this for a university project.

ok...it looks like just applying 1366.9w/m2. The we must apply the factor (1AU)^2/(Xsun-Xcell)^2

Hi! nice toolbox. I have a question. Is it corrected for the actual distance between the Sun and the surface element? (1AU)^2/(Xsun-Xsurf)^2
thnaks!

This is indeed very helpful toolbox but could you please also add the reflectance data for this year or for future in this tool box?
