In 2019, the 18th World Meteorological Congress and the 30th Session of the Intergovernmental Oceanographic Commission (IOC) Assembly of UNESCO jointly endorsed the establishment of the Joint WMO-IOC Collaborative Board (JCB).
The JCB serves as a high-level advisory and coordination mechanism designed to foster strategic collaboration between the World Meteorological Organization (WMO) and the IOC. Its primary objective is to enhance synergies across the full value chain of Earth system observation and prediction. This includes strengthening cooperation in areas such as observational systems, data management and access, research, forecasting capabilities, global and regional services, and capacity development.
The JCB replaced the former Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM).
