COOP+ EU Project aims to foster the cooperation between international environmental Research Infrastructures. ICOS, EMSO, EISCAT, among other RIs, participate in this project, in a consortium composed by 9 EU institutions. EGU concentrations a wide range audience, with several RIs participating in a way or another in EGU activities. Therefore, COOP+ coordination team considers it is a good opportunity to synchronize the General Assembly with the conference, this way reducing travels and allowing the attendance of project collaborators from all over the world.
