What we do

Building partnerships between measurement specialists and the climate & ocean observation communities to enhance metrological best practice across Europe and beyond.

The 2015 Paris Agreement seeks to limit the rise in temperature of the Earth to less than 2 °C, with a target of less than 1.5 °C, above pre-industrial levels to reduce the risks and impacts of climate change. To achieve this, many countries have policies to achieve ‘net zero’ emissions by the middle of the century. This extremely challenging goal requires immediate, sustained and significant annual decreases in greenhouse gas emissions and a simultaneous increase in carbon sinks (in soils, forests and ocean phytoplankton).

The ocean is an example of the challenging balance between human and environmental needs. Many people depend on the oceans for food security, tourism, transportation, heritage and climate regulation. Many are also vulnerable to sea level rise and from the increased storms generated by a warming ocean and atmosphere. We have over-exploited the seas, with fish stocks reducing, mineral resources over-extracted, plastics found even at the deepest parts of the ocean, and with coral reefs and other unique habitats dying from increasing temperatures and acidity.
Governments, international organisations, businesses and charities, need to make complex, inter-related decisions to meet ambitious targets for environmental sustainability and social and economic development. Such decisions rely on the availability of reliable environmental data information services that have been quality assured.

Metrology provides expertise for accurately and reliably monitoring essential climate variables (ECVs) and essential ocean variables (EOVs) over the long timescales needed to be able to detect and understand climate trends.

Who we are


The European Metrology Network (EMN) for Climate and Ocean Observation will support the integration of measurement science with climate and ocean observation research in three environmental themes: atmosphere, ocean, and land & Earth Observation. In each theme, metrologists will connect with those making observations to understand the associated measurement challenges. Working together, the EMN can offer practical support and calibration services, develop and implement quality assurance frameworks, and offer training and resources to ensure that global climate and ocean observations can be used with confidence to support a variety of end applications.

The EMN for Climate and Ocean Observation is one of several EMNs established by EURAMET, the European Association of National Metrology Institutes. The EMNs have been set up to help realise their aim to ensure Europe has a world-leading metrology capability, based on high-quality scientific research and an effective and inclusive infrastructure, that meets the rapidly advancing needs of end users.

The EMN for Climate and Ocean Observation has as members the National Metrology Institutes and associated Designated Institutes in Europe. Other organisations are encouraged to affiliate with the network as network partners.
