Detailed explanation-1: -Because Earth is much cooler than the Sun, it re-radiates energy as longwave, lower-energy wavelengths than it absorbs. This absorbed energy is re-radiated as infrared radiation, which we feel as heat.
Detailed explanation-2: -Outgoing Long-wave Radiation (OLR) is electromagnetic radiation of wavelengths from 3–100 m emitted from Earth and its atmosphere out to space in the form of thermal radiation. It is also referred to as up-welling long-wave radiation and terrestrial long-wave flux, among others.
Detailed explanation-3: -The sun emits shortwave radiation because it is extremely hot and has a lot of energy to give off. Once in the Earth’s atmosphere, clouds and the surface absorb the solar energy. The ground heats up and re-emits energy as longwave radiation in the form of infrared rays.
