WP13: Data handling and distribution

Lead: UU
UU 6 months

This work package determines how the EISCAT_3D data system will be implemented on the e-infrastructure which currently exists in northern Scandinavia or is planned for the near future. Carried out by Uppsala University (UU), hosting the Swedish National Infrastructure for Computing (SNIC) together with Umeå University, third party of UU, engages with the national providers of networking, storage and high performance computing to ensure that the requirements of the project can be optimally satisfied. According to the modified plan, the activities in this work package started in March 2013 and continued until the end of the project.

WP13 was in the beginning hampered by the uncertainties in the performance specification and in addition experienced some delays, because the legal entity responsible for the Swedish National Infrastructure for computing changed from VR to Uppsala University as host of SNIC during the project.  Through SNIC becoming more involved it was possible to make some very useful additional connections to e-infrastructure providers in the host countries.  The work package has been de-scoped to six months and this time has been well spent.

WP12: System control

Lead: EISCAT
EISCAT 8 months

This work package determines the changes that are needed to be implemented in the existing EISCAT system control software (EROS) in order to control a system on the scale envisaged for EISCAT_3D with sufficient flexibility and programmability.

The work plan for this work package has been significantly changed compared to the original work plan, since the development of an operating system for a specific hardware cannot be made within the scope of the Preparatory Phase project. Instead the focus is turned towards general considerations needed for a system of the scale of EISCAT_3D. This work also suffered from delays in other work packages and some of the work originally planned turned out to be impossible because other packages were not far enough along. Nonetheless, this work package has been generally successful and has gone smoothly.

WP11: Software theory and implementation

Lead: UOULO
UOULO 45 months

The purpose of this work package is to develop the software modules required for data processing and analysis tasks of the EISCAT_3D radar system. The development is needed because of the complexity of a distributed phased-array incoherent radar system compared to earlier systems.

WP11 has made lots of progress in developing solutions for this tasks but it could have gone even further in integration of EISCAT_3D hardware and software, if there had been faster progress in the other work packages (especially WP 7). Nonetheless, this work package has been generally successful and has gone smoothly.

WP10: Aperture synthesis imaging radar

Lead: UiT
UiT 24 months

The major activity of this work package is the determination of the optimum number of outlying passive phased array antennas and their optimum localisation (antenna configuration) in order to fulfill the imaging (across-beam) spatial resolution criteria of the Aperture Synthesis Imaging.

WP10 was also a follow-on activity from the FP6 study and has been successfully finalized several months before the end of the project.

WP9: Transmitter development

Lead: IRF
IRF 30 months, EISCAT 4 months

In this work package, important parts of the EISCAT_3D radar transmitter subsystem are designed and evaluated. These particular areas of the transmitter design were planned to be addressed already during the FP6 Design Study were left unfinished because of a lack of manpower and time.

WP9 was intended to be a limited activity, following up on work done in the FP6 design study. The work has been finalized more than a year ago.

WP8: Antenna, front end and time synchronization

Lead: LTU
LTU 48 months, NI 2 months

The antennas, array layout, receiver front end, and calibration system all play important roles in setting the achievable system performance. The objective of this work package is to produce designs of these hardware elements which will be suitable for industrial consideration, and to identify the people who are capable of constructing them.

WP8 outcome is in good shape, with a good design and working prototypes being tested. The work that involved SMEs and resulted in prototyping carried out in WP14.

WP7: Digital signal processing

Lead: UOULU
UOULO 22.3 months, NI 10 months

In this work package, the techniques of signal processing using software-defined radio (SDR) receiver systems is developed to be suitable for parallel processing of signals from a phased array radar. The development is done via laboratory set-ups of hardware and software, followed by a field trial of the developed units, to establish their reliability and performance. 

WP7 has suffered from organisational and intellectual property problems and delays in the planned field testing. They were only carried out during the last months of the project. Part of the delay is caused by revisiting some fundamental design issues (such as the concept of a locally bistatic system) which, in hindsight, proved to be unnecessary.

WP5: Consortium building

Lead: EISCAT
EISCAT 21 months, UiT 6 months, VR 4 months

In this work package, the consortium of funding bodies which will support the new infrastructure is identified, a firm overview of the costs of constructing and operating the new infrastructure is obtained and confronted to the commitments available, and the organisational structure of EISCAT is re-examined, in order to verify whether the new consortium can be accommodated.

WP5 was successful in identifying some potential new partners and especially in co-ordinating the existing partners into a consortium to fund the project. Five countries are now preparing coordinated funding proposals and their national applications are at various stages in the review process. The work package also established the path of dialogues with e-infrastructure stakeholders and with other European research infrastructures. The effort needed to support national funding applications in the membership countries was underestimated by far and the activities were partly funded outside of the project.

WP4: Outreach activities

Lead: EISCAT
EISCAT 24 months

In order for EISCAT_3D to be successful, it is imperative that the project should establish and maintain a strong outreach activity, addressing the provision of publicity information to the general public, opinion-formers, and particularly aiming at the students and young people who will form the next generation of EISCAT users.

WP4 has probably originally been underestimated in terms of the work required. The outreach to opinion formers and decision makers turned out to be more important than originally thought and especially more time-consuming. Nonetheless, this work package has been generally successful and has gone smoothly.

WP3: Science planning and user engagement

Lead: UOULU
UOULU 16 months, STFC 11 months, EISCAT 2 months

This work package covers all those activities needed to engage with the new users whose activities will come within the scope of the enhanced facility. More than simply contacting new users, a key activity will be gathering their requirements for the science topics that they will address, and the different types of new experiment which they would like to run. Work package 3 started at the beginning of the project and continued until July 2014.

The WP organized a number of meetings with Science Working Groups on specific topics and user engagement workshops and participated in the organization of the EISCAT_3D User meetings that the project organized every year. A meeting together with representatives for the technical Work packages in the project in early 2013 resulted in a detailed list of requirements on the radar system from the scientific point of view. In addition to the different research areas addressed with EISCAT_3D the meetings also were devoted to discussion with the space weather and modeling communities and to discussions on using EISCAT_3D in combination with other instruments.

The WP3 has been a demanding project because it needed to cover all potential uses of the new radar.  The outcome is a voluminous science case document and a number of contacts with new user groups. The work package has gone smoothly.
