GRILLE
Definition
- The objective of the Grille spectrometer (GRILLE) experiment was to determine the vertical distribution profiles of trace constituents, on a global scale, between 15 and 150 km altitude through spectroscopic observations of the Earth's limb in the wavelength range characteristic of the vibrational-rotational lines of atmospheric constituents. GRILLE was flown on the Space Shuttle as part of the Atmospheric Laboratory for Applications and Science (ATLAS 1) and on Spacelab 1. In addition to the atmospheric species previously studied with the GRILLE instrument on the Spacelab 1 flight, the instrument has also studied the hydroxyl radical (OH) on the ATLAS 1 flight. The equipment consisted of an infrared spectrometer with a telescope and a cooled infrared detector. The spectrometer operated in the wavelength range from 2.5 to 10 microns at a resolution better than 0.1 per cm. The grille on the instrument is a 15 x 15 mm square with a minimum step of 0.1 mm. The GRILLE instrument was not be flown on subsequent ATLAS flights. Further information about the ATLAS-1 mission can be found at: "http://wwwghcc.msfc.nasa.gov/atlas1.html" IDN_Node: USA/NASA (en)
