Channels selection technique for contemporary IR-spectrometers
Numerical Weather Prediction (NWP) systems have been using satellite images for data assimilation with the demonstrated positive impact on their forecast performance. However contemporary advanced infrared sounders provide thousands of radiance data at every observation location. Thus, the number of individual pieces of information ("spurious channels") is not usable in an operational NWP context. In this connection, we have investigated the possibilities of choosing an "optimal" subset of data, which would be relatively small. Several methods have been tried to select a set of the most useful channels for Infrared Atmospheric Sounding Interferometer (IASI).
