World Weather Watch (WWW)
Programme
The World Weather Watch coordinates development,
implementation and operation of observing systems,
telecommunication facilities, and data-processing and
forecasting centres - owned and run by Members - to
make available meteorological and related geophysical
observations and forecasts needed to provide efficient
services in all countries.

The Global Observing
System of the WWW
comprises surface and
space-based
subsystems;
data obtained are
transmitted via the
Global Telecommunication System
to the Global DataProcessing &
Forecasting System,
where required
information and
products are produced
and sent to the users.

Global Observing System:
• Provides observations for all other WMO
programmes (including aviation, climate,
agriculture, environment, disaster prevention and
mitigation)
• Operated by National Meteorological Services
• Data requirements evolve with technology
Typical daily coverage of surface observations from land (red) and VOS (blue) stations
At present over 10 000 manned and automatic weather stations on
land and about 7 000 voluntary observing ships (VOS) at sea provide
measurements and observations
Space-based subsystem of the Global Observing System

Scheme of a typical mission of an Argo float
A new global observing component in the oceans, the Array for Real-time Ocean
Floats (Argo), was introduced; 624 Argo floats were operational in 2003
