Sentences with phrase «absorption band around»

Not exact matches

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.

Also, I would very much like someone knowledgeable to tackle Norm Kalmanovitch's posts from around 2.30 pm — in particular his assertions regarding saturation of the absorption band and measurements of OLR.

That big dip around 15 microns is due to the absorption / emission band of CO2.

Carbon dioxide (CO2) is mostly transparent to radiation, but it has a few absorption bands, the most important of which is around 12μ to 17μ, in the range where the Earth outputs longwave radiation.

Water vapour causes most absorption in the near infrared from 0.7 um to 6 um (but with C0 2 bands at 2.7 um and 4.3 um), there is strong C02 absorption around 15 um, then intense water vapour absorption takes over right through to about 1 mm wavelength

This method has been tested in a 250 - cm − 1 region around 15 µm where the CO2 absorption overlaps the tail of the water vapor rotation band.
