The main activities of the Commission for Basic Systems (CBS) are related to the development, implementation and operation of integrated systems for observing, data processing, data communication and data management, and to the provision of public weather services, in response to requirements of all WMO Programmes and opportunities provided by technological developments. CBS is the lead Technical Commission for the overall World Weather Watch Programme (WWW), the WMO Space Programme and the Public Weather Services Programme.
CBS’s work is accomplished through a Management Group and four Open Programme Area Groups (OPAG) on Integrated Observing System, on Information System and Services, on Data-Processing and Forecasting System and on Public Weather Services. Each OPAG relies on several Expert Teams and an Implementation Coordination Team to develop and coordinate programme outputs and to guide global implementation. Rapporteurs and Coordinators have been established for specific subjects, especially WMO cross-cutting programmes.
The Commission meets every two years in an ordinary or extraordinary session.
