ILAS : Improved Limb Atmospheric Spectrometer


      The ILAS instrument, developed by the Japanese Environment Agency (NIES), was launched on the ADEOS 1 satellite on 17 August 1996. It was a visible/infrared spectrometer, recording atmospheric absorption spectra by solar occultation and its main objective was to monitor stratospheric ozone in the polar regions.
