Technical Note: Intercomparison of ILAS-II version 2 and 1.4 trace species with MIPAS-B measurements
The Improved Limb Atmospheric Spectrometer (ILAS)-II sensor aboard the Japanese ADEOS-II satellite was launched into its sun-synchronous orbit on 14 December 2002 and performed solar occultation measurements of trace species, aerosols, temperature, and pressure in the polar stratosphere until 25 Oct...
