Resolution 673 (WRC-07) “Radiocommunications use for Earth observation applications“

Resolution ITU-R 55 “ITU studies of disaster prediction, detection, mitigation and relief”

Currently, radio-based applications such as remote sensors are the main source of information about the Earth’s atmosphere and surface.  For 135 years, there has been excellent collaboration and partnership between WMO and ITU. Whilst WMO focuses its efforts on meeting the needs for environmental information and the corresponding radio frequency spectrum resources, ITU, as international steward of the spectrum, allocates the necessary radio frequencies to allow the interference-free operation of radio-based applications and radiocommunication systems (terrestrial and space) used for climate monitoring and prediction, weather forecasting and disaster early warning and detection.

The primary goal of this seminar is to provide information and facilitate exchange of the experience of National Meteorological Services and Radio-Frequency Spectrum Management Authorities on the use and further development of radio-based space and terrestrial systems and applications employed for weather, water and climate monitoring and the relevant radio-frequency spectrum management activities. The seminar will be conducted in English.
