Thirteenth EISCAT-3D User Meeting

      EISCAT Scientific Association                                               

13th EISCAT_3D User Meeting, 2021

  The EISCAT_3D (E3D) project has been officially started with an opening event on September 7, 2017, and is now constructing stage 1. User meetings have been regularly held. Presently  they are held online (Zoom) with a cadence of about 2-3 months. A 13th User Meeting took place on June 15, 2021, from 13 to 17 CEST.  As usual, the meeting 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 general subject of the 13th E3D User meeting is the application of E3D for "classical" ionosphere and upper atmosphere science. We'll stick to the traditional scheme with short presentations followed by questions and discussion. Submissions of titles/short abstracts are welcome. Most  of the presentation slides from the two previous meetings, 
11th E3D UM and 12th E3D UM are linked at the meeting page.

Information and user particpation

Information about EISCAT and especially the E3D User Meetings is distributed via the mailing list,, moderated by EISCAT. To subscribe, pse contact Ingemar Häggström. Several specialized channels are at the EISCAT Slack-workspace, offering  a frame for relatively spontaneous discussions on any relevant subject. To get an invitation, pse contact Carl-Fredrik Enell.


A registration was required by filling  the Google form.  The form also allows the enter the title and abstract of presentation or discussion point that the user would like to see in the meeting programme. 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 are stored as long as E3D User meetings are regularly held, unless specific removals are requested.


Contributions on any E3D related subject can be submitted. Especially encouraged for this 13th meeting are discussions on applications of volumetric imaging for "classical" ionosphere and upper atmosphere science, e.g. magnetosphere-ionosphere coupling, ion drifts and neutral winds, TIDs and gravity waves, and on the scientific analysis of E3D data. Any subject is welcome.

The preliminary programme with approximate timings 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 exchange of personal data such as names and email addresses 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 presenters agree.

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 20112012, 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.
