Meridional distribution feature of minor constituents as observed by IMG sensor aboard ADEOS satellite Original Research Article

Interferometric Monitor for Greenhouse gases (IMG) sensor aboard the Advanced Earth Observing Satellite (ADEOS) is a Fourier Transform type infrared spectrometer (FT-IR) which was developed aiming to measure the greenhouse gases in the atmosphere, particularly in the troposphere. It was operated for about 7 months from November 1996 up to the end of the life time of the ADEOS on June 1997, and measured over 138000 terrestrial thermal emission spectra which are available for the retrieval analysis. A cloud detection and correction method based on the analysis of the initially retrieved temperature profiles were presented. Using the cloud correction method, meridional distribution of temperature and minor constitutents were preliminarily analyzed.
