The purpose, structure, and principles of the information system for processing, analysis, and storage of the data of optical measurements in the stratosphere are considered. The system is still under development and is intended for revealing the processes and regularities connected with the ozone and ozone layer in the stratosphere. Various data are used for analysis and processing: the lidar sounding data (altitude distributions of the ozone, temperature, and aerosol scattering ratio), the passive sounding data (total ozone content, distribution and total content of nitrogen dioxide), as well as different model data. We present a functional block diagram of the system and consider the interrelations of the composing subsystems. The operation algorithm and the interface of the system are described. The prospects of development and further improvement of the system are considered including the use of the World Wide Web.
