Abstract :
In order to determine some spectral wavelength specifications of the Global Imager (GLI), the GLI sensor team´s Technical Support Group (TCSG) has performed many experimental calculations. An advanced accurate and efficient radiative transfer scheme called GLI Signal Simulator (GSS) was used for these experiments. These calculations were applied to the 3.7 μm band and 6.7 to 7.5 μm band to determine the central wavelength and/or bandwidth of each channel. The results show that 3.7 μm is better than 3.9 μm to estimate nighttime sea surface temperature and to determine cloud particle size; the combination of 6.7 μm, 7.3 μm and 7.5 μm is the best choice for water vapor profiling
