In the past, there has been debate concerning the form of water vapor responsible for this absorption. This debate was resolved in the 1980s with the development of the CKD continuum model (Clough et al. 1989), which was the water vapor continuum.1–5 Most observations of water vapor continuum absorption have been made in the atmo-spheric infrared window from 8 to 12 µm, where the con-tinuum produces signiﬁcant absorption over long atmo-spheric paths and thereby plays a critical role in atmospheric 2013-01-09 region, absorption is dominated by the water vapor continuum. height.

The window regions in the microwave are of critical importance for Earth remote sensing and data assimilation.

the water lines increases linearly with the number density of water vapor, while continuum attenuation increases as the square of the number density. Consequently, the relative proportion of the total absorption due to the continuum increases linearly with the number density. Fig. 1. This figure is a revised version of Fig. 10 of [4].

The solid line represents a linear regression (described in text) to all Burch's recent water vapor data for the 8-30-,um region. Continuum absorption is explained semi-empirically as the overlap of absorption due to many absorption lineswith centers far from the continuum region. A good example occurs in the 10- μm windowregion, where continuum absorption by water vaporcan be particularly important. Compareband absorption, line absorption.

The measurements were made with both long-path absorption cell and spectrophone systems. Water vapor continuum absorp-tion is then quantiﬁed via the spectral residuals, i.e., the dif-ference between simulated and measured spectra.

Another theory, "third-order linear absorption," in which pairs of water molecules cooperatively absorb photons while both molecules undergo transitions in internal The infrared spectrum of water vapor is made up of strongly absorbing bands, consisting of large numbers of individual spectral lines, interspersed by “windows” with much weaker absorption. The absorption in these windows is dominated not by spectral lines, but by the so‐called water vapor continuum, a slowly varying component of absorption that Water vapor plays the dominant role in the propagation of mm and THz electromagnetic waves in the atmosphere, since it has several thousand rotational absorption lines from the mm wave range through the terahertz region up to 5 THz. Also, oxygen gas has a cluster of approximately 25 overlapping lines at 60 GHz and a single line at 120 GHz. The pure water-vapor continuum absorption in the 2.88 to 5.18μm spectral region has been measured using a Fourier-transform infrared spectrometer at a resolution of 0.1cm−1. The water vapour continuum is characterised by absorption that varies smoothly with wavelength, from the visible to the microwave. It is present within the rotational and vibrational–rotational bands of water vapour, which consist of large numbers of narrow spectral lines, and in the many ‘windows’ between these bands. The pure water-vapor continuum absorption in the 2.88 to 5.18μm spectral region has been measured using a Fourier-transform infrared spectrometer at a resolution of 0.1cm−1. The conventional description of water vapor infrared absorption is applied, in which the absorption is modeled in two parts consisting of local line absorption and the remaining residual absorption, which has become known as the water vapor continuum.
