Information from the Unified State Fund of Data on the State of the Environment and its Pollution (USFD), which consolidates large amounts of data from hydrometeorological observations and pollution monitoring, is one of the key factors affecting the life of modern world society and the stable economic development of every state on the planet Earth. This effect is due to the presence of particularly dangerous hydrometeorological phenomena and adverse weather conditions that can cause social and economic damage. In this regard, the tasks of collecting, accounting, long-term storage and timely provision of such information to consumers of various sectors of economic activity for use in decision-making remain relevant. This article discusses the key aspects of the information technology of the USFD, which is formed as a result of the activities of the Federal Service of Russia for Hydrometeorology and Pollution Monitoring (Roshydromet). As a result of the work, a description of the technological process of maintaining USFD, statistical data on the demand and use of USFD information and a new documentary information search system solving the problem of accounting and long-term storage of USFD information resources are presented. The system was developed using modern information technologies, international standards for describing information resources and taking into account the experience of foreign organizations engaged in activities similar to Roshydromet. The direction of further development of digital technologies for operational public service with information products created on the basis of verified USFD information resources is also outlined.
