[1] Total absorbed radiation (TAR), the sum of SNR [shortwave net radiation] and LDR [longwave downward radiation], represents the total radiative energy available to maintain the Earth's surface temperature and to sustain the turbulent (sensible and latent) heat fluxes in the atmosphere.

This 3W / m ^ 2 of absorbed radiation that the models currently under represent, chiefly from earlier observed spring snow melts while they allegedly «match» the 20th century climate, will be added as the models project the next 100 years, catching up with the snow melt, an addition of heat comparable to the projected CO2 forcing.

The dark clouds themselves would be warmed by the absorbed radiation and some of absorbed energy would be re-radiated toward the surface.

All absorbed radiation must be returned to space, except for very minor imbalances (e.g., of the order of currently estimated 0.9 W / ^ 2) during forcing by CO2, solar changes, aerosols, or other climate drivers.

Whereabouts are those early 1950s precision measurements to be found which demonstrate that adding more carbon dioxide really would change how the atmosphere absorbed radiation?

The energy enters these water bodies at the surface when absorbed radiation is converted into heat energy.

The flaw in the article is that it does not take into account that the absorbed radiation is outgoing, but the emitted radiation go in all directions.

Part of the absorbed radiation warms the surrounding air, a process that tends to stabilize the air over a city, which in turn increases the probability of higher pollutant concentrations.

Here is the IPCC on stratospheric cooling: «When the CO2 concentration is increased, the increase in absorbed radiation is quite small and increased emission leads to a cooling at all heights in the stratosphere.»

1) In the phrase «radiation from the sun,» is that the incident or absorbed radiation?

If any absorbed radiation is eventually exactly matched by collision caused emission, the radiation field has to remain constant (again after transients).

This knowledge is not new; the same year as Charles Darwin published «The Origin of Species», John Tyndall, an Irish scientist, published a paper in 1859 describing how he measured the absorption of infrared radiation in his laboratory, finding that CO2 and water vapour absorbed the radiation, whereas nitrogen and oxygen, the main gases in the atmosphere, do not.

Finally, the film of electrons would absorb the radiation and reemit it as heat.

«Just as clouds reflect radiation efficiently, they also absorb radiation efficiently and re-emit that energy back to warm the surface.»

Tinetti says the earlier studies could be a product of the planets» bright sides cooking to the same temperature throughout, which makes atmospheric molecules less likely to absorb radiation from below.

Pendry discovered that the electrical properties allowing the material to absorb radiation came not from the carbon per se but from the shape of its long, thin fibers.

These all absorb radiation at wavelengths in the mid-infrared between 3 and 10 micrometres.

The fact that air travelers absorb radiation is not news.

The frameworks absorb radiation better than tissue, delivering an extra dose of radiation to the tumor.

While scientists have long been hunting for clues to its composition, the fact that it does not emit or absorb any radiation and interacts with visible matter only through gravity makes it next to impossible to detect and study.

The only aerosol type we can measure more or less directly is black carbon, since we have an instrument that can detect radiation - absorbing particles, and black carbon is the main particle type that absorbs radiation.
