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.

Satellite radar altimetry measures the time taken by a radar pulse to travel from the satellite antenna to the surface and back to the satellite receiver. This measurement yields a wealth of information that can be used for a wide range of applications – in particular, for understanding sea-level rise.
World-class scientists are meeting in the Azores this week, at the "25 Years of Progress in Radar Altimetry" Symposium, to discuss the latest developments in our understanding of Earth's surface variations observed by altimetry.
