Primary Input
Include Atmosphere Reflection
W m⁻²
Surface Albedo
Albedo = Reflected from surface Incident on surface
0 / 140 = 0.30
Color Key:
Yellow: Short-wave Solar Radiation
Red: Long-wave Infrared Radiation
PLANET SURFACE Atmosphere Incoming 200 Reflected from atmosphere 60 Reflected from surface 42 Escaping 140 Greenhouse return 84 radiated by surface 224
Intensity Values
Incoming 200 W m⁻²
Reflected from atmosphere 60 W m⁻²
Reaching surface 140 W m⁻²
Reflected from surface 42 W m⁻²
Greenhouse return 84 W m⁻²
radiated by surface 224 W m⁻²
Intensity Balance (Surface)
Note: These equations are not included in your formula booklet, but you can figure them out by looking at the direction of the arrows.
Greenhouse Effect: In this simulation the atmosphere absorbs 60% of surface radiation and re-emits it down.
