JCOMM, the Joint Technical Commission for Oceanography and Marine Meteorology, is an intergovernmental body of technical experts that provides a mechanism for international coordination of oceanographic and marine meteorological observing, data management and services, combining the expertise, technologies and capacity building capabilities of the meteorological and oceanographic communities. The creation of this Joint Technical Commission results from a general recognition that worldwide improvements in coordination and efficiency may be achieved by combining the expertise and technological capabilities of World Meteorological Organization (WMO) and UNESCO’s Intergovernmental Oceanographic Commission (IOC). JCOMM coordinates, and develops and recommends standards and procedures for, a fully integrated marine observing, data management and services system that: (a) uses state-of-the-art technologies and capabilities; (b) is responsive to the evolving needs of all users of marine data and products; (c) and includes an outreach programme to enhance the national capacity of all maritime countrie. JCOMM aims to maximize the benefits for its Members/Member States in the projects, programmes and activities that it undertakes in their interest and that of the global community in general.
