Introduction of the WMO Preliminary Position on the WRC-23 Agenda
Introduction of the WMO Preliminary Position on the WRC-23 Agenda
Eastern Session: February 21 07:00 UTC
&
Western Session: February 23 15:00 UTC
Background
WMO Members through their National Meteorological and Hydrological Services (NMHSs) and supporting agencies, including operators of space-based observing systems, make available a wide range of essential services to observe weather, water, climate and related environmental events.
The information gathered through these observations is vital for the global community and contributes to ensuring safety of life and property and in the longer term to implementing the global development agendas, such as the 2030 agenda for Sustainable Development, the Paris Climate Agreement and the Sendai Framework for Disaster Risk Reduction.
The observing networks provided by WMO Members form the backbone of the WMO Integrated Global Observing System (WIGOS) and are critically dependent on the use of radiofrequencies for the sensing and dissemination of data and information.
In this context, Resolution 673 of the International Telecommunication Union (ITU) World Radiocommunication Conference (Geneva, 2012) observes that:
- Earth observation data are essential for monitoring and predicting climate changes, for disaster prediction, monitoring and mitigation, for increasing the understanding, modelling and verification of all aspects of climate change, and for related policymaking
- Many observations are performed over the entire world which require spectrum-related issues to be considered on a worldwide basis
- Earth observations are performed for the benefit of the whole international community and the data are generally made available at no cost
and resolves to:
- Continue to recognize that the use of spectrum by Earth observation applications has a considerable societal and economic value
- Urge administrations to take into account Earth observation radio-frequency requirements and in particular protection of the Earth observation systems in the related frequency bands
- Encourage administrations to consider the importance of the use and availability of spectrum for Earth observation applications prior to taking decisions that would negatively impact the operation of these applications
The development of new, mass-market and value-added radio applications is putting increasing pressure on the frequency bands used for meteorological purposes.
This presents potential risks of limiting meteorological and other related application, but also opportunities for enhancing observations.
WMO remains committed to work with ITU towards optimizing the use of the radio-frequency spectrum for the benefit of the global community.
The preliminary WMO positions related to the agenda items of WRC-23 developed by the WMO Expert Team on Radio-Frequency Coordination (ET-RFC) and approved at the second session of the Commission for Observation, Infrastructure, and Information Systems (INFCOM-2) can be accessed in all UN languages here.
