Abstract
The CLIM (Cloud Imager) infrared camera, currently being defined, has same channels as AVHRR and has been designed to assist sounders by spotting areas of clear sky from a satellite. The article outlines a simulation of CLIM, based on real data, and presents its estimated performances for different spectral band configurations associated with a cloud detection algorithm. The study shows that up to 40% more cloud-free zones can be explored by a sounder supported by such an imager, compared with the same sounder pointing fixedly at the nadir.
