- Cloud detection is an important field in meteorology and remote sensing, due to clouds role in meso- and macroscale weather processes. Most of the dangerous weather events, such as hail fall, strong wind or severe storm can be forecasted or predicted using satellite imagery. MODIS data are very useful in nephological analysis as they cover vast majority of Earth surface and provide hiperspectral images with a short revisit time. Tests of RGB compositions of MODIS bands were performed, to look for model compositions for cloud detection. Three best compositions have been chosen: RGB 17/18-6-26, RGB 30-23-8, RGB 34-1-17. They allow to delimitate clouds and identify their family, type and (in some cases) specie. MODIS cloud masks accuracy has been checked, based on model RGB compositions. Results show that each mask detects different family or type of clouds, and accuracy and precision of this process depends on the mask parameters. For proper cloud delimitation an assistance of a qualified meteorologist is required.
