Short summary
Cirrus and contrails affect Earth’s energy balance with a lot of remaining uncertainty. The balance between solar and terrestrial radiation is delicate to calculate, and factors such as cloud optical depth, shape, and Sun position are crucial to estimate the effect of those clouds on radiation. Also, often neglected three-dimensional paths of radiation, or 3D effects, may be important to account for at the climatic scale.
