GEONETCast

GEONETCast is a global network of satellite-based data dissemination systems providing environmental data to a world-wide user community. The current partners within the GEONETCast initiative include the China Meteorological Administration (CMA), the National Oceanic and Atmospheric Administration (NOAA), the World Meteorological Organization (WMO) and EUMETSAT, as well as many prospective data provider partners.

Aim of GEONETCast

GEONETCast is a milestone in the emerging Global Earth Observation System of Systems (GEOSS) that is being coordinated by the intergovernmental (GEO), and is designed to put a vast range of essential environmental data at the fingertips of users around the globe. This user-driven, user-friendly and low-cost information dissemination service aims to provide global information as a basis for sound decision-making in a number of critical areas, including public health, energy, agriculture, weather, water, climate, natural disasters and ecosystems. Accessing and sharing such a range of vital data will yield societal benefits through improved human health and well-being; environment management, and economic growth.

Within the existing framework, GEONETCast is already partially realising this goal with environmental data exchange and data delivery available in Europe, Africa and the Americas. An additional data exchange is now being established covering the Asia Pacific region.

GEONETCast Infrastructure

The conceptual idea of a global GEONETCast implementation is that several regional centres take on the responsibilities for establishing a satellite-based regional dissemination system — based upon Digital Video Broadcast (DVB) technology — and provide complementary services to a common user community.

GEONETCast Broadcast Streams


			EUMETCast is the EUMETSAT contribution to GEONETCast with coverage over Europe, Africa and the Americas. Established in 2004, EUMETCast has more than 2,000 registered reception stations with more than 1,600 users benefiting from the environmental data it provides.

			CMACast is the China Meteorological Administration’s contribution to GEONETCast. CMACast utilises the AsiaSat 4 satellite beam to broadcast data and products to a user community in the Asia Pacific region.

			Broadcast covering the Americas, managed by NOAA.
