Abstract: A satellite data processing aircraft icing detection and display mechanism comprises a communication link coupled with an earth-imaging satellite containing a terrestrial-directed imagery sensing system, which conveys data associated with multiple images representative of characteristics of the earth's atmosphere in a viewed terrestrial area. A digital imagery data processor is coupled to the communication link, and is operative to process the data to provide an indication of intensity and height of potential areas of aircraft icing. An icing display subsystem is coupled with the digital imagery data processor and is operative to generate a multi-pixel map image showing the geographical location, intensity and height of an identified aircraft icing layer.
