Open Opportunities for Researchers
ESA is pleased to announce the reopening of the Announcement of Opportunity (AO) call for the Aeolus Mission.
Within the framework of its Copernicus missions, ESA is pleased to announce the Sentinel-5 Precursor Calibration and Validation Team Call.
The Open Science Earth Observation (OSEO) call offers to scientists the opportunity to exploit at no cost a full archive of optical EO data for science, applications and technological innovation, by offering services which exploit state of the art ICT.
The S3VT call is open to relevant and interested groups and individuals worldwide; group responses are particularly welcome.
Interested users may - at any time - submit proposals for the use of Swarm validated Level 1b and Level 2 data through a dedicated interface.
