Sentences with phrase «thermal radiation absorption»

And this process is not linear, as the processes resultant from a net ongoing energy change due a massive increase in external input (a multi million year change — increase — in lower atmospheric thermal radiation absorption and re radiation, in the sense of our geologically recent evolved «temperate» earth climate and global energy balance is massive) is not linear.

Not exact matches

Absorption of thermal radiation cools the thermal spectra of the earth as seen from space, radiation emitted by de-excitation is what results in the further warming of the surface, and the surface continues to warm until the rate at which energy is radiated from the earth's climate system (given the increased opacity of the atmosphere to longwave radiation) is equal to the rate at which energy enters it.

The CO2 doesn't alter climate by affecting thermal mass; it affects climate by retarding the efficiency of infrared radiation, and it has important IR absorption bands in places where water is ineffective.

As a result, the carbon dioxide absorption bands at 4.26 and 7.52 microns contribute little to the absorption of thermal radiation compared to the band at 14.99 microns.

We also know quite accurately the spectral absorption characteristics for the absorbing gases, and how cloud and aerosol particles interact with thermal radiation.

The Greenhouse Effect refers to the absorption and re-radiation of IR thermal radiation by molecules including CO2, methane, water vapor, fluorocarbons, nitrous oxides, and SF6.

Check out the Schwarzschild equation so you understand out to properly calculate both absorption and emission of thermal radiation by CO2.

@Vaughn https://judithcurry.com/2012/12/04/multidecadal-climate-to-within-a-millikelvin/#comment - We know quantitatively, albeit roughly, from the work of Tyndall in the 1850s the extent to which CO2 itself... blocks the passage of thermal radiation; these days we infer this much more precisely from the HITRAN tables of spectral absorption / emission lines.

I can feel thermal radiation, I believe CO2 has a measured IR absorption spectrum, I believe a CO2 molecule is not a bottomless pit of energy that can be filled without ever spilling over, and this predictable spilling over is measured from spectrometers on satellites and the ground, therefore there is a CO2 greenhouse effect whose net effect on the climate is of some small and as yet imprecisely known size.

It is entirely possible that volcanos show a transient thermal absorption response before they turn into upper atmosphere radiation reflectors.

We know quantitatively, albeit roughly, from the work of Tyndall in the 1850s the extent to which CO2 itself, with no feedbacks, blocks the passage of thermal radiation; these days we infer this much more precisely from the HITRAN tables of spectral absorption / emission lines.

However I have to agree that the demonstration is nowhere near quantitative enough to infer much about absorption by CO2 of thermal radiation from Earth's surface.

Reflected radiation is a very different scenario than absorption and thermal radiation.

On top of that and regardless of any absorption / emission properties there is thermal radiation that is only due to the fact that charges that compose the molecules accelerate by vibration and collision and this property is general for any form of matter.

The increased absorption due to higher CO2 decreased the outgoing radiation within a portion of the thermal radiation spectrum (10 - 11 microns).

«Because the solar - thermal energy balance of Earth [at the top of the atmosphere (TOA)-RSB- is maintained by radiative processes only, and because all the global net advective energy transports must equal zero, it follows that the global average surface temperature must be determined in full by the radiative fluxes arising from the patterns of temperature and absorption of radiation.»

There is a fundamental relationship (Gustav Kirchhoff's 1859 law of thermal radiation) that equates the emissivity of a surface with its absorption of incident light (the «absorptivity» of a surface).

Each higher and cooler layer in turn emits thermal radiation corresponding to its temperature; and much of that also escapes directly to space around the absorption bands of the higher atmosphere layers; and so on; so that the total LWIR emission from the earth should then be a composite of roughly BB spectra but with source temepratures ranging ove the entire surface Temeprature range, as well as the range of atmospheric emitting Temperatures.

There is little need to consider other than the troposphere, just knowing that it acquires thermal energy from the stratosphere and from absorption of downwelling and upwelling radiation.

It's a presumption that radical alteration of the atmosphere upward in terms of its thermal energy absorption and re radiation would NOT ultimately and significantly change our climate in a similarly radical, or at least major, way.

The physics that must be included to investigate the moist greenhouse is principally: (i) accurate radiation incorporating the spectral variation of gaseous absorption in both the solar radiation and thermal emission spectral regions, (ii) atmospheric dynamics and convection with no specifications favouring artificial atmospheric boundaries, such as between a troposphere and stratosphere, (iii) realistic water vapour physics, including its effect on atmospheric mass and surface pressure, and (iv) cloud properties that respond realistically to climate change.

One assumes the critics accept the physical reality of absorption and re-emission of thermal radiation by GHG.

The most easily understood interaction between aerosols and climate is the direct effect (scattering and absorption of shortwave and thermal radiation), which is discussed in detail in Chapter 2.

The absorption interval of CO2 molecules covers less than 20 percent of the spectrum of thermal radiation of the Earth's surface, while atmospheric moisture absorbs thermal radiation rather uniformly over the entire spectrum.

One very little understood property of matter (atoms, molecules, etc) is that their real life emittance (thus absorption) changes as a function of their internal temperature and outside temperature (thermal radiation field).
