The bilingual (Russian and English) research portal SP@DIS is designed as an integrated set of distributed but coordinated topical web sites, combining classical multi-media information with research databases, models and analytical tools for on-line use, and visualisation. Traditional sites of the portal related to different parts of atmospheric sciences: atmospheric components and their properties studied in atmospheic spectroscopy, chemistry, radiation. Each site consists of relevant experimental data, information and knowledge. Data can be either of a generic nature, or refer to the selected case study sites covered in detail. The representation system relies on Internet technologies for easy access to the information resources, scientific graphics and tabular representation, dialog systems (menus) and service programs. The latter include topical glossaries, textbooks,  user's guide, and links to external Internet resources.
