The flux level of the continuous spectrum is called the continuum level, and at an emission line the spectrum rises above this level, while at an absorption line

The continuum As is well known, the spectral line profiles in a wing absorption dominates in atmospheric transparency differ for different absorption bands [4–7]; therefore, windows. the continuum (used in MT CKD model) obtained The comparative smoothness of the continuum on the basis of the unified line profile model, and absorption curve turned out to be a cause of the experimental data in

It arises as a result of pairwise interaction between molecules. The spectra of dipoleless molecules do not exhibit resonant absorption lines in the millimeter and far infrared ranges, provided quadrupole or higher order absorption can be neglected. absorptionline spectra. We can think of stars as a hot continuum source with a "cool" atmosphere of absorbing gas. The wavelengths that get absorbed depend on the chemical make up of the gas in the stellar atmosphere.

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.

Continuum removal was applied to the selected absorption features. Continuum removal normalizes reflectance spectra in order to allow comparison of individual absorption features from a common baseline (Kokaly, 2001). The continuum is a convex hull fitted over the top of a spectrum to connect local spectrum maxima.

continuum absorption A region of continuous spectral absorptionby a gas that shows no apparent line structure. Continuum absorption is explained semi-empirically as the overlap of absorption due to many absorption lineswith centers far from the continuum region. 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 continuum absorption by laboratory samples of pure H 2 O and of H 2 0 + N 2 throughout the infrared and millimeter regions has been studied.
