The Project

Cos4Cloud (Co-designed citizen observatories for the EOS-Cloud) is a European Horizon 2020 project to boost citizen science technologies.

One of the biggest challenges of citizen science is the quality of data, as well as maintaining the citizen observatories used to collect this data. Cos4Cloud is addressing these challenges by developing thirteen technological services to improve citizen science platforms.


Different research centres, companies and organizations from eight different countries participate in Cos4Cloud.


The Cos4Cloud’s team is made up of experts from different fields and organizations. All of them are key to the success of the project.
