Improved Limb Atmospheric Spectrometer (ILAS)

摘要

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$-$MIN@1$/, 11.76 $mu@m - 6.21 $mu@m) for O$-3$/, HNO$-3$/, NO$-2$/, N$-2$/O, H$-2$/O, CH$-4$/ and CFC11, and the other is for visible band (753-784 nm, O$-2$/ A band) for aerosols, temperature and air density measurement. ILAS will be onboard the ADEOS spacecraft and will observe high-latitude (N55-70, S63-87) ozone layer after February 1996 over 3 years with high vertical resolution ($LSEQ@2 km).!4
