Bond Albedo vs Reflected Flux
Planet Albedo
Albedo quantifies how reflective a planet is. A value of 0 means all light is absorbed; 1 means all is reflected.
Formula
A = F_reflected / F_incident
The absorbed fraction is (1 - A), which determines how much stellar energy heats the planet.
Example Calculation
Earth reflects about 100 W/m2 out of 1361 W/m2 incident.
- 01A = F_reflected / F_incident
- 02A = 100 / 1361
- 03A = 0.0735
- 04This is geometric albedo at one angle; Bond albedo integrated over all angles is about 0.30
