Abstract
The Interferometric Monitor for Greenhouse Gases (IMG) uses Fourier transform spectrometry to measure the top of the atmosphere spectral radiance between 3.3 μm and 14 μm in 3 separate bands. It was launched aboard the Japanese ADEOS satellite in August 1996, and has an unapodized spectral resolution of 0.05 cm-1. IMG spectral radiance measurements over different geographical spectral resolution of 0.05 cm-1. IMG spectral radiance measurements over different geographical regions are compared with standard line-by-line radiative transfer model calculations. CO retrieval and comparison between synthetic spectra calculated by FASCOD3 and IMG observations during the WINter Clouds Experiment (WINCE) are discussed as a case study. Preliminary analysis indicates that the retrieved CO from IMG spectral radiance measurements agrees with in-situ measurements made by the Climate Monitoring and Diagnostics Laboratory of the National Oceanic and Atmospheric Administration (NOAA/CMDL) at the nearby Park Falls monitoring site.
