ILAS (Improved Limb Atmospheric Spectrometer) on board ADEOS worked satisfactorily during the period from November 1996 to June 1997 until the end of ADEOS operation. It provided huge amount of data regarding high-latitude stratospheric ozone layer both in the southern and northern hemispheres. The present paper aims at describing briefly the data processing algorithms and data processing status, and demonstrating some early results of the Antarctic ozone hole measurements. The ozone and nitrous oxide distribution show clearly the structures of ozone hole in an altitude-longitude cross section.
