Contributing to advances in climate research

Thousands of buoys and floats worldwide are equipped with Argos transmitters, sending regular information via the Argos system to help scientists understand and predict climate change.


Argos offers ocean data telemetry services for a broad spectrum of applications.

Hydrology: Managing water resources and related risks

Hydrological platforms installed in strategic places use the Argos system to transmit data on water levels (floods, rivers, tides, rainfall, etc.) to scientists and government authorities.

The measurements collected by these automatic beacons are also made available to international programs and help the international community improve the management and distribution of water resources on our planet.

Typical users of the data are scientists from various research institutions, who use the data to study topics ranging from pollutant transport by sea ice to global climate change.

Operationally, the data are used for forecasting the weather and ice conditions.

Meteorology: Collecting atmospheric data in-situ

Throughout the world, thousands of meteorological stations at sea or on land send information via the Argos system to help scientists understand and predict climate changes.

These data from isolated and sometimes inaccessible zones are a very useful source of information for understanding the environment and climate change.

Most of these data contribute to components of the World Climate Research Program (WCRP) as well as to operational meteorology.

More than 70% of Argos data are shared by the oceanography and meteorology communities which assimilate them into numerical forecasting models via the World Telecommunications System (WTS) of the World Meteorology Organization (WMO).
