At the Earth’s surface, emission is simply a function of surface temperature: the higher it is, the more longwave radiation is emitted. It depends on how much energy is acquired from the Earth’s surface, water vapor, and cloud cover.
Q. What wavelength of radiation does the Earth emit?
Outgoing Long-wave Radiation (OLR) is electromagnetic radiation of wavelengths from 3–100 μm 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.

Q. What is Outwave longwave radiation?
OLR (Outgoing Longwave Radiation) is a measure of the amount of energy emitted to space by earth’s surface, oceans and atmosphere. OLR observations are made via the Advanced Very High Resolution Radiometer (AVHRR) instrument aboard the NOAA polar orbiting spacecraft.
Q. Is solar radiation shortwave or longwave?
Figure 5. Earth’s radiation budget. Incoming solar radiation is shortwave, ultraviolet, and visible radiation; outgoing Earth radiation is long wave infrared radiation.
Q. What is the difference between shortwave radiation and longwave radiation?
What is the difference between long-wave and short-wave infrared radiation? Short-wave infrared energy comes directly from the sun, but is not felt as heat. It converts into heat when it strikes an object. Long-wave infrared energy is the heat radiated from an object, which has received short-wave infrared radiation.
Q. What is another name for shortwave radiation?
Shortwave radiation (SW) is radiant energy with wavelengths in the visible (VIS), near-ultraviolet (UV), and near-infrared (NIR) spectra.
Q. Why is solar radiation short wave?
Downwelling short-wave radiation at the surface has a component due to the direct solar beam, and a diffuse component scattered from atmospheric constituents and reflected from clouds.
Q. Do clouds reflect longwave radiation?
Deep convec- tive clouds emit little longwave radiation at the top but much at the bottom. They also reflect much of the incoming shortwave radiation. Their cloud greenhouse and albedo forcings are both large, but nearly in balance, resulting in neither warming nor cooling.
Q. Which cloud has highest albedo?
Fresh snow
Q. Do clouds respond to the environment?
Clouds will respond to climate change in ways that further heat the planet, a new study suggests. Clouds cool the planet by reflecting incoming radiation from the sun. They heat it by trapping outgoing radiation from the planet’s surface.
Q. Do clouds absorb shortwave radiation?
The high, thin cirrus clouds in the Earth’s atmosphere act in a way similar to clear air because they are highly transparent to shortwave radiation (their cloud albedo forcing is small), but they readily absorb the outgoing longwave radiation.
