Abstract

Program overview, scientific targets and instrument design of the Improved Limb Atmospheric Spectrometer (ILAS) is described. The ILAS has two grating spectrometers for solar occultation measurement: one is for measurement of infrared band (850-1610 cm^-1, 11.76 micrometers - 6.21 micrometers ) for O₃, HNO₃, NO₂, N₂O, H₂O, CH₄ and CFC11, and the other is for visible band (753-784 nm, O₂ A band) for aerosols, temperature and air density measurement. ILAS will be onboard the ADEOS spacecraft and will observe high-latitude (N55-70, S63-87) ozone layer after February 1996 over 3 years with high vertical resolution (less than or equal to 2 km).
