Terms of Reference

  1. Keep under review allocations of radio-frequency bands and assignments of radio-frequencies to meteorological activities for operational requirements (telecommunications, instruments, sensors, etc.) and research purposes, in close coordination with other technical commissions, especially CIMO and the CBS/OPAG on IOS;
  2. Coordinate with WMO Members, with the assistance of the WMO Secretariat, to:
    1. Ensure the proper notification and assignment of frequencies used for meteorological purpose;
    2. Determine their future use of the radio spectrum for meteorological purpose;
  3. Keep abreast of the activities of the Radio-communication Sector of the International Telecommunication Union (ITU-R), and in particular of the Radio-communication Study Groups, on frequency matters pertaining to meteorological activities, and represent WMO in ITU-R work;
  4. Prepare and coordinate proposals and advice to WMO Members on radio-regulation matters pertaining to meteorological activities with a view to ITU Radio-communication Study Groups, Radio-communication Assembly, World Radio-communication Conferences and related regional/global preparatory meetings;
  5. Facilitate the coordination between WMO Members for the use of frequency bands allocated to meteorological activities with respect to:
    1. Coordination of frequency use/assignments between countries;
    2. Coordination of frequency use/assignments between various radio communication services (e.g. meteorological aids and data collection platforms (DCPs)) sharing the same band;
  6. Facilitate the coordination of WMO with other international organizations which address radio spectrum planning, including specialized organizations (e.g. CGMS, the Space Frequency Coordination Group (SFCG) and regional telecommunication organizations, such as the European Conference of Postal and Telecommunications Administrations (CEPT), the Inter-American Telecommunication Commission (CITEL), and the Asia-Pacific Telecommunity (APT));
  7. Assist WMO Members, upon request, in the ITU coordination procedure of frequency assignment for radio-communication systems sharing a frequency band with meteorological radio communication systems.
