Improved Limb Atmospheric Spectrometer 2 (ILAS-2)

NSSDCA ID: 2002-056A-04

Mission Name: Adeos 2


ILAS-2 (Improved Limb Atmospheric Spectrometer 2) maps the vertical distribution of O3, NO2, HNO3, H2O, CFC-11, CFC-12, CH4, N2O, and ClONO2, as well as the distribution of temperature and pressure, all in the stratosphere. It observes the absoprtion spectrum in Earth's atmospheric limb in the 3-13 micron wavelength band, and in the 753-784 nm band of the occulting Sun. The altitude resolution is 100 m.
