Albedo vs Emissivity The short answer
Albedo governs how much incoming shortwave solar energy a surface rejects; emissivity governs how efficiently it radiates longwave heat away. A full energy balance needs both — albedo alone tells you only half the story of why a surface is the temperature it is.
