Technical Commissions

Technical Commissions

There are eight Technical Commissions responsible for studying meteorological and hydrological operational systems, applications and research. They establish methodology and procedures and make recommendations to Executive Council and Congress. 

There are eight technical commissions, composed of experts designated by Members, responsible for studying meteorological and hydrological operational systems, applications and research. They establish methodology and procedures and make recommendations to the Executive Council and the Congress. The technical commissions usually meet once every four years – except for the Commission for Basic Systems, which holds an extraordinary session in between. The President and Vice-President of each commission are elected at these meetings.

The eight WMO technical commissions are composed of experts in the field of the specific commission. These are designated by Members for their scientific expertise not to act as representatives on their state.

Commission for Aeronautical Meteorology (CAeM)

The Commission for Aeronautical Meteorology is the driving force behind the Aeronautical Meteorology Programme.

Commission for Agricultural Meteorology (CAgM)

The Commission for Agricultural Meteorology (CAgM), the driving force behind the Agricultural Meteorology Programme, is to provide guidance in the field of agricultural meteorology by studying and reviewing the available science and technology.

Commission for Atmospheric Sciences (CAS)

The Commission for Atmospheric Sciences supports research in atmospheric science through the Global Atmospheric Watch and World Weather Research Programmes in order to reduce and mitigate natural disasters, protect the environment and enhance understanding and response to environmental change.

Commission for Basic Systems (CBS)

The Commission for Basic Systems oversees the development, implementation and operation of integrated systems for observing, data processing, data communication and data management. It guides the work of the World Weather Watch, Public Weather Services and WMO Space Programmes.

Commission for Climatology (CCl)

The Commission for Climatology leads international technical activities under the World Climate Programme in view of applying climate information and knowledge to support sustainable socio-economic development and for environmental protection.

Commission for Hydrology (CHy)

The Commission for Hydrology (CHy) addresses basic hydrological observation networks, water resources assessment, flood forecasting and warning, flood and drought management and adaptability to climate variability and change and promotes the exchange of technology and capacity building. 

Commission for Instruments and Methods of Observation (CIMO)

Established by the International Meteorological Organization, the Commission for Instruments and Methods of Observation (CIMO) ensures the accuracy of weather observation by facilitating the creation of international standards and, thus, the compatibility of measurements.

Joint WMO-IOC Commission for Oceanography and Marine Meteorology (JCOMM)

The Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM) is an intergovernmental body for international coordination of oceanographic and marine meteorological observing, data management and services.
