Understanding the magnitude, timescale and impact of climate change is one of the most critical issues of our time and requires worldwide collaboration.

The European Metrology Network (EMN) for Climate and Ocean Observation will help to ensure that Europe meets its environmental targets and stays at the forefront of international action on climate change. Promoting collaboration and cooperation across Europe in a wide range of scientific fields, the EMN will connect measurement scientists to those making and using observations. The network will enable observers to address the measurement accuracy targets required to monitor essential climate and ocean variables.
