Short summary
The evolution of the climate system is strictly related to its radiative response to changes in surface and atmospheric processes. Through the analysis of the Earth’s emission spectrum measured by satellite instruments, we show that the radiative response to El-Niño Southern Oscillation is wavenumber-dependent, highlighting the role of key climate variables. This makes this analysis particularly suitable for climate models evaluations.
