New Radio Regulations protect vital meteorological radio frequencies

Press Release Number:

Geneva, 27 November 2015 (WMO) - Radio frequencies which are vital for weather forecasts, disaster warnings and climate monitoring will remain available to the meteorological community and protected from interference from other applications thanks to decisions taken by the World Radiocommunication Conference 2015 (WRC-15).

The World Meteorological Organization (WMO) today welcomed the outcome of WRC-15, which revised and updated the Radio Regulations, the international treaty governing the use of the radio-frequency spectrum.  The month-long conference is sponsored by the International Telecommunications Union and takes place every four years-

WRC-15 reinforced the commitment of previous World Radiocommunication Conferences to the special needs of meteorological and hydrological services, despite competing pressure for scarce radio frequencies from wireless technology and other uses.

The outcome of WRC-15 addressed practically all its major issues of concern, with adequate protection for frequencies used in meteorology and earth observations in general. Electromagnetic spectrum will continue to be available for observing and distributing meteorological and related geophysical information. This is vital to monitor and understand our Earth, atmosphere and oceans and to reduce the risk of weather, climate and water-related disasters.

"WMO is pleased that the World Radiocommunication Conference has recognized the importance of earth observations and the sharing of related information to monitor climate change, which is the cause of melting ice caps and glaciers, increasing sea levels and warmer oceans, with record global temperatures and more extreme weather events," said WMO Secretary-General Michel Jarraud.

"We need radio frequencies to receive electromagnetic signatures to increase understanding of our environment and of atmospheric changes. This is important for both climate change mitigation and adaptation," said Mr Jarraud.

Besides the protection of frequencies, several WRC-15 resolutions called for WMO participation in a number of studies in the next four-year cycle leading to the next World Radiocommunication Conference in 2019, when radio regulations will be revised and updated again.

The Chair of the WMO Steering Group on Radio Frequency Coordination (SG-RFC), Jose Arimatea de Sousa Brito (Brazil) paid tribute to WMO's longstanding radio frequency coordination activities, with the support of group members and WMO secretariat staff; the excellent preparation for WRC-15, and the coordinated participation of SG-RFC experts during the four weeks of discussions and decisions.

"As the requirements of the ICT industry will increase, the threat for the scientific spectrum remains," said Mr de Sousa Brito. "WMO will continue to be engaged in the protection and management of radio frequencies, as well as in the allocation and/or identification of additional spectrum needed for meteorological operation and research," he said.
