Current Calls

The Network of Resources (NoR) call is linked to the Open Science Earth Observation (OSEO) initiative and offers to research, development or pre commercial users which are of scientific or value adding nature the opportunity to exploit EO data collocated in a cloud environment using Resource Tier and Platform Tier Services.
The call is open to users from ESA Member States participating to the Earth Observation Envelope Program (EOEP-5).
The evaluation of eligible user requests is performed by ESA, with the subsequent sponsoring provided by ESA and the following external entities: CloudSIGMA, CREODIAS. SOBLOO.

The Open Science Earth Observation (OSEO) call offers to scientists the opportunity to exploit at no cost a full archive of EO data for science, applications and technological innovation, by offering Third Party services which exploit state of the art ICT.

The call is permanently open in priority to scientists from ESA, European Union member states and Africa until the ESA allocated resources are exhausted.

ESA is pleased to announce the reopening of the Announcement of Opportunity (AO) call for the Aeolus Mission.
The objective of the current reopening is
  • to invite worldwide scientists, new groups and individuals, to participate in Aeolus CAL/VAL throughout the mission lifetime.

Please note that proposals already submitted/confirmed for the other calls released in 2007 and 2014 remain valid and do not need to be resubmitted.

Funding of the activities solicited through this AO shall be covered by national/institutional resources. As a CAL/VAL PI or co-PI, access to Aeolus product quality information will become available to you first-hand and before the official product release. Furthermore, you will be given the opportunity to quickly learn cooperate directly with other Aeolus CAL/VAL PIs and to perform joint activities.

Within the framework of its Copernicus missions, ESA is pleased to announce the Sentinel-5 Precursor Calibration and Validation Team Call (S5PVT) that aims to engage leading expertise for the Calibration and Validation of the Sentinel-5 Precursor (S5P) in the mission validation team, providing independent experimental data, analysis and recommendations to critically assess the end-to-end performance of the instrument and its products. The main payload of S5P is TROPOMI (TROPOspheric Monitoring Instrument), a push broom imaging spectrometer realized by ESA in collaboration with the Netherlands Space Office (NSO). S5P is expected to provide information on atmospheric variables in support of European policies and Copernicus services. The S5p satellite was launched on 13 October 2017 and will provide over 7 years data to the user community.

In the framework of a Copernicus collaborative agreement ESA and EUMETSAT is opening a call "To engage world-class validation expertise and activities to complement Sentinel-3 routine validation activities and ensure the best possible outcomes for the Sentinel-3 Mission". The call is open to relevant and interested groups and individuals worldwide; group responses are particularly welcome.
The call is implemented as a rolling call with distinct deadlines for proposal submissions on a regular basis.

ESA is offering all scientists with the possibility to perform bulk processing and/or validation of their own algorithms exploiting the large ESA earth-observation archive together with ESA available GRID computing and
dynamic storage resources.
