Se dit des bandes de longueur d'onde comprises entre 1,1 et 2,25 micromètres.

CONT

infrarouge de courte longueur d'onde est situé entre le proche infrarouge (PIR) et l'infrarouge moyen (IRM). L'IRCL est utilisé notamment pour l'étude de la végétation hétérogène ou clairsemée, pour l'étude de l'humidité superficielle et pour celle des minéraux altérés.

Record 8 2004-06-02

English

Subject field(s)
  • Atmospheric Physics
DEF

Distortion of the atmospheric circulation of a smaller scale than the long waves on which it is superposed and through which it moves.

A short wave moves in the same direction as that of the prevailing basic current through the troposphere. The angular wave number of short waves ranges between eight and twenty.

Key term(s)
  • short-wave

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Perturbation de la circulation atmosphérique d'échelle moindre que celle des grandes ondes, auxquelles elle se superpose et le long desquelles elle se déplace.

Spanish

Campo(s) temático(s)
  • Física de la atmósfera
DEF

Deformación de la circulación atmosférica en escala menor que la de las ondas largas, a las que superpone y entre las cuales se desplaza.

Subject field(s)
  • Scientific Instruments

  • Astrophysics and Cosmography
CONT

Using the Short Wavelength Spectrometer on ISO, they have found large amounts of gas in the debris disks around the stars beta Pictoris, 49 Ceti, and HD135344 by directly observing the lowest transitions of H2. These mid-infrared wavelength lines from molecular hydrogen are quite weak, which simplifies their interpretation but makes them hard to see. ISO was the first cryogenic telescope equipped with spectrometers that could search for H2, and our data illustrate the powerful capabilities of high resolution infrared spectroscopy from space ...

CONT

Les éléments qui composent la vapeur et la poussière de la comète Hale-Bopp rayonnent à des longueurs d'onde caractéristiques dans l'infrarouge, dont un grand nombre ne peuvent être observées sans risque d'erreur que dans l'espace. L'équipe de chercheurs a tiré parti de l'avantage exclusif qu'offre ISO de pouvoir analyser des émissions sur une large gamme de longueurs d'onde, allant de 2 à 200 microns, en utilisant trois des instruments de la sonde : le spectromètre à courte longueur d'onde SWS, un autre spectromètre à courte longueur d'onde intégré au photomètre ISOPHOT et le spectromètre à grande longueur d'onde LWS.
