Tenth EISCAT-3D User Meeting

EISCAT Scientific Association

EISCAT_3D User Meeting 2020/21

The EISCAT_3D (E3D) project has been officially started with an opening event on September 7, 2017, and is now constructing stage 1. A 11th user meeting was scheduled to take place with physical attendance in Uppsala, Sweden. As a result of the pandemia and measures to constrain it, the plans for the 11th meeting had to be revised. We will go for online (Zoom) meetings of about half a day duration, with a monthly to bi-monthly cadence. As usual, the meetings should provide a forum for interested scientists who may or may not be directly involved in the design and construction of the E3D project, and also for persons working more with its administrative, logistic, and technical aspects.

The initial online E3D user meeting will take place on December 16, 13-17 CET. A next meeting is foreseen for January 2021.

The suggested general subject of the 11th E3D User meeting is software interfaces between E3D and users, for scientific analysis of E3D data and perhaps also for radar operations. We'll stick to the traditional scheme with short presentations followed by questions and discussion. Submissions of titles/short abstracts are welcome.

This announcement was updated on December 4, 2020.

Registration

A registration is required by filling this Google form. The names and email addresses of registered persons will be used to provide the Zoom link and other updates about the meeting by email. They will be stored as long as E3D User meetings are regularly held, unless specific removals are requested.

Programme

Contributions on any E3D related subject can be submitted. Especially encouraged for this 11th meeting are discussions on software interfaces between E3D and users, and on the scientific analysis of E3D data. An ad-hoc programme committee of volunteers might be asked to help if many submissions are received and some need to be postponed to a later user meeting.

The preliminary programme is

Practical Information

The workshop will use the Zoom tool licensed by the Uppsala University, The server is operated by Uppsala University which assures that no data exchange with third parties occurs. We do not intend to record the meeting but will make presentation slides publicly available also for some time after the meeting, if the presenter agrees.

EISCAT_3D, a short description

More information can be found at the E3D web site.

E3D is a planned next generation incoherent scatter radar facility, based on phased-array technology and multiple radar sites. The EISCAT_3D proposal was accepted on the ESFRI Roadmap of large-scale European research infrastructures in December 2008.

The EU, EISCAT, the Rutherford-Appleton Laboratory (UK), the University of Tromsø (Norway), the Luleå Technical University (Sweden), and the Swedish Institute of Space Physics (Sweden) financed and undertook the EISCAT-3D design study. The results of the study were presented at the first E3D User Meeting 2009.

A four year long Preparatory Phase of E3D funded by the European Commission under the call FP7-INFRASTRUCTURES-2010-1 started on 1 October 2010. The Preparatory Phase work has been performed by a consortium consisting of 8 institutions: the EISCAT Scientific Association as the coordinator, University of Oulu, Finland, Luleå University of Technology, Sweden, Swedish Institute of Space Physics, Sweden, University of Tromsø, Norway, Science and Technology Facilities Council, UK, Swedish Research Council, Sweden, and National Instruments, Belgium.

Preparatory Phase actions were presented at User Meetings in 2011, 2012, 2013, and 2014. A prominent outcome is the Science Case for a E3D facility. The Preparatory Phase ended in September 2014. In the mean time the E3D proposal now foresees a staged approach, with stage 1 having a core site with transmitter and two receiving sites.

In October 2015 the Horizon 2020 project “EISCAT_3D: Preparation for Production” (EISCAT3D_PfP) had its kick-off, and it was active until August 2017. Results have been collected, and notably a test subarray was developed and built at the EISCAT site in Ramfjordmoen.

After an opening ceremony September 7, 2017, the final development and construction of E3D stage 1 has been going on. The three sites of stage 1 are Skibotn, Norway, Kaiseniemi, Sweden, and Karesuvanto, Finland. Major contracts for the Antenna Unit, the First Stage Receive Unit, and the Sub-Array Transmit Unit have been signed with ECRIEE, China and with DA-Design, Finland. The first measurements for scientific use are expected to be possible in 2022.
