Bond Albedo vs Reflected Flux
Formel
## 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.
Lösungsbeispiel
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
Häufig Gestellte Fragen
What is the difference between bond albedo and geometric albedo?
Geometric albedo measures reflectivity at zero phase angle (full illumination). Bond albedo integrates over all phase angles and wavelengths, giving the total reflected fraction.
Which solar system body has the highest albedo?
Enceladus, Saturn's icy moon, with an albedo near 0.99 due to its bright ice surface.
How does albedo affect habitability?
Higher albedo means less absorbed energy and a cooler surface. Planets need the right albedo to maintain liquid water.
