Collecting weather, climate, ocean and water data

Our observation network has more than 11,000 pieces of equipment. This technology can be found in the sea, on land, in the sky and in space.

It collects data for our public weather information and the computer models that inform our forecasts and warnings.

Some observations become part of our climate data, tracking climate variability and change.
