update Definition ([LAC data is not available and is no longer collected as part of the EO-1 Extended Mission.]

The Linear Etalon Imaging Spectral Array/Atmospheric Corrector (LEISA/AC) is an infrared camera. Images from the AC can 
be used to remove the effects of the atmosphere from surface pictures obtained by instruments such as the Advanced Land 
Imager (ALI) on EO-1 and Landsat. Observing the surface through the atmosphere is conceptually the same as viewing the 
bottom of a lake through cloudy water. The AC provides data on the amount of atmospheric water vapor. These data can be 
used to clear the view. The AC on EO-1 will be the first use of a dedicated instrument to per- form this function on a 
real-time basis. This instrument will provide scientific return both in terms of improved imagery and hyperspectral sensing 
capabilities. It will also test a number of new technologies. Because the AC is small and adaptable to different spacecraft
 configurations, it is a bolt-on instrument, which can be attached to any future Earth imaging spacecraft. The LEISA AC 
 instrument was developed by Goddard's Applied Engineering and Technology Directorate (AETD). AETD will provide open 
 access to U.S. industry regarding the design and performance of the LEISA AC instrument with the explicit purpose of 
 expediting technology transfer to the commercial sector.
