Measurement of the water vapour vertical profile and of the Earth’s outgoing far infrared flux
Our understanding of global warming depends on the accuracy with which the atmospheric components that modulate the Earth’s radiation budget are known. Many uncertainties still exist as regards the radiative effect of water in the different spectral regions, among which is the far infrared, where very few observations have been made. An assessment is shown of the atmospheric outgoing flux obtai...
متن کاملRecent advances in measurement of the water vapour continuum in the far-infrared spectral region.
We present a new derivation of the foreign-broadened water vapour continuum in the far-infrared (far-IR) pure rotation band between 24 μm and 120 μm (85-420 cm(-1)) from field data collected in flight campaigns of the Continuum Absorption by Visible and IR radiation and Atmospheric Relevance (CAVIAR) project with Imperial College's Tropospheric Airborne Fourier Transform Spectrometer (TAFTS) fa...
متن کاملThe Far-Infrared Spectrum of Deuterium Iodide.
We recently described an investigation of the far-infrared (FIR) spectrum of hydrogen iodide, HI, which resulted in an accurate set of rotational and I electric quadrupole parameters for the molecule in its XS (v 5 0) state (1). In this Note, we report an extension of this work to the deuterated form of the molecule, DI. The spectrum of deuterium iodide was recorded using the third-order tunabl...
متن کاملThe influence of chain dynamics on the far-infrared spectrum of liquid methanol-water mixtures.
Far-infrared-absorption spectroscopy has been used to study the low-frequency (<or=100 cm-1) intermolecular modes of methanol in mixtures with water. With the aid of a first-principles molecular-dynamics simulation on an equivalent system, a detailed understanding about the origin of the low-frequency IR modes has been established. The total dipole spectrum from the simulation suggests that the...
متن کاملThe far-infrared vibration–rotation–tunneling spectrum of the water tetramer-d8
The far-infrared vibration–rotation–tunneling spectrum of ~D2O!4 has been measured in the spectral region near 2.04 THz. Observation of additional transition doublets with a constant 5.6 MHz spacing in a parallel ~c-type! spectrum extends the first detailed study of this cluster @Science 271, 59 ~1996!#. Three possibilities are explored for the origin of this small splitting: tunneling between ...
