Paper Abstract

Improved Limb Atmospheric Spectrometer (ILAS) on board the Advanced Earth Observing Satellite (ADEOS) obtained 8-months data for stratospheric ozone layer over the high-latitude regions in both the southern and northern hemispheres. Main parameters observed by ILAS were vertical profiles of ozone, nitrogen dioxide, nitric acid, nitrous oxide, methane, water vapor, aerosol extinction coefficient (at 780 nm), temperature, and pressure. Products from ILAS measurements were validated with correlative measurement data. The instrument and data processing scheme will be overviewed, and some results of validation and preliminary scientific analyses will be presented.
