European Environment Agency (EEA) - EIONET group of in-situ data experts

Copernicus, the European Earth Observation and Monitoring Programme, brings together data collected in space, on the ground, in the sea and in the air for the benefit of citizens and the environment. The programme provides six services including the monitoring and forecasting of the state of the environment on land, at sea and in the atmosphere, emergency responses activities in and outside of Europe, and climate change and security services.

The basis for these services is made up of two components: space and in-situ observations.

While space data and its derived products are widely known and freely accessible via the Copernicus web site, (, in-situ data are often collected by specific monitoring programmes by national authorities or dedicated organisations. Examples of in-situ data include data from sensors placed on the banks of rivers, tall towers, carried on weather balloons or airplanes, pulled through the sea by ships, and drifting in the ocean on floats or buoys.
In situ data are used to calibrate, verify and supplement the information provided by satellites, which is essential in order to deliver reliable and consistent data over time.
The Copernicus in-situ component includes contributions of the Member States to the Copernicus programme, as a significant part of the data and monitoring infrastructure is owned and operated by national governments.
The aim of the EIONET expert group is to map the in-situ data landscape, compare what is available against requirements, to identify gaps, support the provision of cross-cutting data and manage partnerships with data providers to improve access and use conditions.
In the project, space4environment is responsible for assessing geospatial in-situ data in the land domain.
