Absorptions bands in the Earth's atmosphere created by greenhouse gases and the resulting effects on transmitted radiation. In spectroscopy, an absorption band is a range of wavelengths, frequencies or energies in the electromagnetic spectrum that are characteristic of a particular transition from initial to final state in a substance.
To simplify these challenges, differential optical absorption spectroscopy has gained some popularity, as it focusses on differential absorption features and omits broad-band absorption such as aerosol extinction and extinction due to rayleigh scattering. This method is applied to ground-based, airborne, and satellite-based measurements.
In spectroscopy, a Soret peak or Soret band is an intense peak in the blue wavelength region of the visible spectrum. The peak is named after its discoverer, Jacques-Louis Soret . [ 1 ] The term is commonly used in absorption spectroscopy , corresponding to a wavelength of maximum absorption (electromagnetic radiation) ranging around 400 nm in ...
The HITRAN spectroscopy database lists more than 37,000 spectral lines for gaseous H 2 16 O, ranging from the microwave region to the visible spectrum. [5] [12] In liquid water the rotational transitions are effectively quenched, but absorption bands are affected by hydrogen bonding.
An example of spectroscopy: a prism analyses white light by dispersing it into its component colors. Spectroscopy is the field of study that measures and interprets electromagnetic spectra. [1] [2] In narrower contexts, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum.
The individual absorption spectra of major greenhouse gases plus Rayleigh scattering are shown in the lower panel. [1] An atmospheric window is a region of the electromagnetic spectrum that can pass through the atmosphere of Earth. The optical, infrared and radio windows comprise the three main atmospheric windows. [2]
