EUMETCast is a scheme for dissemination of various (mainly satellite based) meteorological data operated by EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites. The main purpose is the dissemination of EUMETSAT's own data, but various data from other providers are broadcast as well. EUMETCast is a contribution to GEONETCast and IGDDS (WMO's Integrated Global Data Dissemination Service) and provides data for GEOSS and GMES.
EUMETCast satellite includes data and derived products from the geostationary Meteosat satellites, Meteosat-7 (over the Indian Ocean), 8, 9 and 10 and the Metop-A & B and NOAA polar orbiting satellites, plus data from other meteorological programmes, such as Jason-2 (the Ocean Surface Topography Mission).
Examples of data and products on EUMETCast satellite:
A range of third-party meteorological and environmental products are also available. The range includes:
A comprehensive list of all products available on EUMETCast can be found in EUMETSAT's product catalogue, known as the Product Navigator.
In 2016 EUMETSAT started a demonstration EUMETCast Terrestrial service, which sends multicast satellite data in Europe via the National Research and Education Network (NRENs) and the GÉANT infrastructure. Only organisations eligible for access to a NRENs can access the service, if the NREN supports multicasting.
The terrestrial service will re-use components familiar to users of the EUMETCast satellite service and then, as for EUMETCast satellite, subscribes to the related multicast channels to receive the data.
EUMETCast uses the DVB-S MPEG2 stream for encapsulating frames (IP over DVB). At this IP layer, IP Multicast techniques are used for distributing the file based content. For this purpose, TELLICAST (an IP multicast software from Newtec (formerly Tellitec)) is used. In 2014 EUMETCast was migrated to a DVB-S2 transponder, which allows for higher bandwidth rates.
