Sentences with phrase «infrared emission spectrum»

Coincident measurements of the infrared emission spectrum of the cloudfree atmosphere at (a) 20 km looking downward over the Arctic ice sheet and (b) at the surface looking upwards.
Okay, one little nit - picky issue with Q2 is that O2 and N2 actually DO absorb infrared radiation, just at shorter wavelengths than matter for the Earth's infrared emission spectrum (3 - 27 microns, with a peak around 9 microns or so).
Okay, one little nit - picky issue with Q2 is that O2 and N2 actually DO absorb infrared radiation, just at shorter wavelengths than matter for the Earth's infrared emission spectrum (3 - 27 microns, with a peak around 9 microns or so).
The latter is aimed for use in the infrared emission spectrum.

Not exact matches

Illuminating the cell with a laser results in the emission of photons with a wavelength in the infrared spectrum range.
A number of similar black hole exploration methods have also been proposed in optical / infrared spectra so far, but one crucial problem is that emissions at these wavelengths are absorbed by interstellar dust particles although the more active black holes contain more dust particles.
Measuring with a spectrometer what is left from the radiation of a broadband infrared source (say a black body heated at 1000 °C) after crossing the equivalent of some tens or hundreds of meters of the air, shows that the main CO2 bands (4.3 µm and 15 µm) have been replaced by the emission spectrum of the CO2 which is radiated at the temperature of the trace - gas.
The infrared radiation hangs around longer than it would have done, some being absorbed by matter, causing heating, which causes higher re-emission (the blackbody spectrum of the whole Earth's emissions moves slightly to a higher energy - temperature profile, in order to balance out the radiation budget of the Earth).
