A surface's albedo is the percentage of incoming solar energy, sunlight, that's reflected off that surface back into space.

一个表面的反照率是入射的太阳能、阳光从这个表面反射回太空的百分比。

Vegetation cover attributes play a major role in surface energy budgets through their impact on photosynthetic processes and albedo.

植被覆盖特征影响光合作用和反照率，是表面能量估计中的主要因素。

This decreased level of reflectivity, or albedo, allowed the surface to absorb more energy from the Sun.
