Regional Warning Centers
At present, there are fourteen Regional Warning Centres distributed around the
globe. These centres are located in China (Beijing)
(Boulder), Russia (Moscow),
(New Delhi ), Canada (Ottawa),
Czech Republic (Prague), Japan
(Tokyo), Australia (Sydney), Sweden
(Lund), Belgium (Brussels), Poland
(Warsaw), South Africa
(Hermanus), South Korea (Jeju) and Brazil (São José dos Campos). The European
Space Agency (Noordwijk) is a collaborative expert centre providing a venue
for data and product exchange for activities in Europe. In addition, the Associate
Warning Centre in France (Toulouse) provides
specialized services to customers, and is affiliated through RWC Belgium. A
data exchange schedule operates with each centre providing and relaying data
to the other centres. The centre in Boulder plays a special role as "World
Warning Agency", acting as a hub for data exchange and forecasts.
The data exchanged are highly varied in nature and in format,
ranging from simple forecasts or coded information up to more
complicated information such as images. An important strength
of the data exchange system is that RWCs often have access to
data from unique instrumentation available from the scientific
community in its region. Exchange through ISES makes these data
available to the wider international scientific and user community.
The prime reason for the existence of the Regional Warning Centres
is to provide services to the scientific and user communities
within their own regions. These services usually consist of forecasts
or warnings of disturbances to the solar terrestrial environment.
The range of the locations of RWCs results in a very large diversity
in the users of these forecasts. An important feature of the ISES
system is that RWCs are able to construct and direct their services
to the specific needs of their own customers.
Users of the services of RWCs include: high frequency (HF)
radio communicators; mineral surveyors using geophysical techniques;
power line and pipeline authorities; operators of satellites and
a host of commercial and scientific users. The increasing sophistication
and sensitivity of modern technology has resulted in a steadily
expanding range of applications where a knowledge of the solar
terrestrial environment is important.
