Abstract :
The Improved Limb Atmospheric Spectrometer (ILAS) launched on board the Advanced Earth Observing Satellite (ADEOS) in August 1996 has been normally working and acquiring data with the solar occultation method for the stratospheric ozone layer in the northern and southern high latitude regions. The data from ILAS is processed to derive profiles of ozone and other gas species as well as profiles of temperature and aerosol information, archived at ILAS & RIS Data Handling Facility (ILAS & RIS DHF) at National Institute for Environmental Studies (NIES), and distributed to science communities. The Retroreflector in Space (RIS) on board the ADEOS is a corner cube mirror with an effective diameter of about 50 cm, which is used for Earth-satellite long path laser absorption measurements of atmospheric gas species concentration. Brief introduction of the ILAS and RIS and some preliminary results of the measurements are presented
