Abstract

Results of conceptual design study of a solar occultation infrared sensor, improved limb atmospheric spectrometer-II (ILAS-II) which will be onboard ADEOS-II spacecraft, is discussed. The ILAS-II will have four grating spectrometers for solar occultation measurement: two are identical to the spectrometers of the ILAS onboard ADEOS to be launched in 1996. To observe ClONO₂, which is a key species that controls catalytic destruction of ozone, an echelle grating spectrometer with 0.14 cm^-1 resolution for the 780.2 +/- 1 cm^-1 region will be added to the ILAS-II. Another new spectrometer will cover the 3 to 5.7 micrometers region to characterize the aerosols such as sulfuric acid aerosols and PSCs as well as to observe the chemical species.
