1 Introduction of RGB Composite Imagery Technique of MSG/SEVIRI in EUMETSAT, and Application to Satellite Imagery of MTSAT-1R SHIMIZU Akihiro Abstract In the neph-analysis technique, the skills required for the interpretation and extraction of necessary information from the imagery include special knowledge and experience. On the other hand, the RGB composite imagery technique" used in Europe is a technique that can help us grasp the phenomenon that catch our attention more effectively and facilitate interpreting, by overlapping and displaying in color the satellite imagery of two or more channels. The knowledge about this technique obtained at EUMETSAT is introduced in this report, and I applied that knowledge to the satellite image of MTSAT-1R and attempted to composite RGB imagery on SATAID. As a result, it was confirmed that the RGB composite imagery of the MTSAT-1R imagery are effective for the identification of the cloud region and the phenomena. It is thought that RGB composite imagery technique will contribute to the work of the neph-analysis because the composite imagery can be displayed by easy operations on SATAID.
