Sentences with phrase «atmospheric radiation spectrum»

Thanks, SoD, but what do you think of this atmospheric radiation spectrum, recorded by Nimbus 4 spacecraft?

Not exact matches

The work is an estimate of the global average based on a single - column, time - average model of the atmosphere and surface (with some approximations — e.g. the surface is not truly a perfect blackbody in the LW (long - wave) portion of the spectrum (the wavelengths dominated by terrestrial / atmospheric emission, as opposed to SW radiation, dominated by solar radiation), but it can give you a pretty good idea of things (fig 1 shows a spectrum of radiation to space); there is also some comparison to actual measurements.

How can the earth be radiating a crude BB type spectrum corresponding to the surface Temperature when Trenberth claims that only 40 W / m ^ 2 escapes to space in the atmospheric window, and folks insist that the main body of the atmosphere (gases) does not emit thermal radiation.

These so - called greenhouse gases absorb infrared radiation, emitted by the Earth's surface, the atmosphere and clouds, except in a transparent part of the spectrum called the «atmospheric window», as shown in Figure 1.2.

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.

The incoming Sun's radiation is 3.5 times greater in intensity than the outgoing Earth's radiation, hence the Sun's infrared is 1.6 times greater in intensity than the Earth's radiation and experiences the same atmospheric absorption spectra as the Earth radiation.

Our recent study has focused on a molecule's radiative efficiency within the atmospheric window region of the IR spectrum, which can be thought of as a molecule's inherent ability to absorb radiation in the atmospheric window.

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.

But for the earth atmosphere apparently based on AIRS satellite observations, as well as computer calculations, what is seen, looking down is a clearly blackbody like radiation spectrum, with holes in it corresponding to various atmospheric components like H2O, CO2, and O3 primarily.
