Abstract: The accurate modeling of continuum absorption is crucial for the so-called window regions of the spectrum, the relatively transparent regions between lines. The window regions in the microwave are of critical importance for Earth remote sensing and data assimilation. Abstract Absolute absorption rates of pure water vapor and mixtures of water vapor and nitrogen have been measured in the laboratory at 350 GHz . The dependence on pressure and temperature has been obtained. Additionally, a water vapor continuum parameter estimation, taking even the previous laboratory measurements from 150 to 350 GHz into account, is performed.

Continuum, Emission, and Absorption Spectra The corresponding spectrum may exhibit a continuum, or may have superposed on the continuum bright lines (an emission spectrum) or dark lines (an absorption spectrum), as illustrated in the following figure. Continuous, emission, and absorption spectra The water vapor continuum absorption spectrum is retrieved using the known absorption in the 2500 cm−1 region as a reference point. It is shown that the continuum absorptions in four windows differ Water vapor continuum absorption in the 3.5-4.0-,um region Kenneth 0. White, Wendell R. Watkins, Charles W. Bruce, Robert E. Meredith, and Frederick G. Smith Measurements of water vapor continuum absorption in the 3.5-4.0-gm region are presented. From observation, the in-band continuum absorption is aligned with the location of the water vapour monomer bands; therefore, any interaction between the absorbing water vapour molecule and another molecule (water vapour or ‘foreign’) that is responsible for this additional absorption must be sufficiently weak so as to permit access to the same rotovibrational modes of monomer transitions and sufficiently brief to cause these transitions to be greatly broadened. The water vapor continuum absorption spectrum is retrieved using the known absorption in the 2500 cm−1 region as a reference point.

The absorption maximum lies around 603 nm, with a cross-section of 5.23 10 −21 cm 2. One of the most common methods for background correction is to use a continuum source, such as a D 2 lamp. Because a D 2 lamp is a continuum source, absorbance of its radiation by the analyte’s narrow absorption line is negligible.

As the energy of X-ray radiation is scanning through the binding energy regime of a core shell, a sudden increase of absorption appears, and such phenomenon corresponds to absorption of the X-ray photon by a specific type of core electrons (eg. 1s electrons of Cu). continuum absorption A region of continuous spectral absorption by a gas that shows no apparent line structure.
