What to look for

NASA CERES observations, 2000–2015 mean. Colours show sunlight reflected by the Earth system in W m⁻². This is outgoing shortwave flux, not incoming solar irradiance or albedo itself.

NASA CERES map of reflected shortwave radiation averaged over 2000–2015, with a 0–385 W m⁻² colour scale.
