Abstract

The Improved Limb Atmospheric Spectrometer (ILAS) is one of the sensors on ADEOS (ADvanced Earth Observing Satellite) which will be launched in early 1996. ILAS has two grating spectrometers designed to measure vertical profiles of high latitude stratospheric constituents such as O₃, CH₄, N₂O, HNO₃, H₂O, NO₂, and CFC-11 (from the IR channel), and vertical profiles of pressure, temperature, and aerosols (from the visible channel), in a solar occultation mode. The basic plan of the ILAS operational data processing system (ODPS) has been established. System integration of the ILAS/ODPS will be defined in a year, and the system will be settled in two years. This paper describes the status of the ILAS instrument manufacturing and the outline of the ILAS/ODPS
