The Caribbean Institute for Meteorology and Hydrology was established in 1967 by the member states of the Caribbean Meteorological Organisation (CMO). It was amalgamated with the Caribbean Operational Hydrological Institute (COHI) in the mid-1980s to form the Caribbean Institute for Meteorology and Hydrology (CIMH), but the name was only officially changed in September 1999 to reflect the dual role of the Institute. Responsibility for the operation of the Institute, which is located in Barbados, rests with the sixteen Commonwealth Governments which comprise the CMO.
