The difference between incoming solar radiation absorbed by Earth and the power of outgoing longwave radiation emitted to space

The Earth's Energy Imbalance (EEI) quantifies the heating occurring by measuring the net difference between the power of absorbed incoming solar radiation and the power of outgoing longwave radiation escaping to space.
