EISCAT_3D Preparatory Phase
This week, we have the last general meeting of the preparatory phase for EISCAT_3D. This project is the next-generation incoherent scatter radar, which will be built in northern Fenno-Scandinavia and, perhaps, beyond. It is an ambitious project, which involved many participants from multiple countries. And, as this particular phase of the project is completed, we are meeting at the Space Physics Institute in Kiruna, Sweden, to discuss the work done, report on the progress made and make plans for the future of this important scientific instrument.
KAIRA has been heavily involved in the project. Although a large multi-purpose facility, capable of carrying out multiple receive-type experiments, it has been used specifically to test certain aspects of the EISCAT_3D proposal. Its deployment garnered useful experience in practical matters regarding the development of a new site and the utilisation and integration of commercially available components within the context of Arctic location and cross-disciplinary application. We have also used KAIRA for new signal processing techniques, such as allowing the lag-profile inversion, and thus accomplishing multibeam, remote-location reception of the EISCAT VHF transmitter signal. This is a critically important step in the construction and operation of \EISCAT for multi-beam, multi-static incoherent scatter radar, and thus true 3D volumetric ionospheric measurement. The KAIRA facility remains operational for on-going EISCAT development and prototyping endeavours.
Undoubtedly, KAIRA will continue to be involved in EISCAT work, and specifically the EISCAT_3D developments. But as this particular part of the project is accomplished, we want to note our involvement and wish the EISCAT Scientific Association all the best for their future goals.

Visitors from Ettus Research and National Instruments at SGO
Yesterday we had Matt Ettus from Ettus Research and Leif Johansson from National Instruments visiting SGO. We had a one-day meeting on mainly EISCAT_3D and KAIRA related things. Naturally, the scope was in the software radio defined technologies and on how to use them with phased-array systems. Hence, today we feature two photos of the meeting.

KAIRA film
At the LOFAR Science Workshop 2014 in Amsterdam, we premièred the KAIRA film. This was produced by SiteEye in conjunction with Sodankylä Geophysical Observatory, U. Oulu, ASTRON, EISCAT, and many others. (Versions with subtitles in many languages will be posted later.)
Enjoy!
UPDATE!
The film is also available with Finnish subtitles (LINK).

LOFAR, EISCAT, SKA... and KAIRA of course!
Today's photograph was from the recent science seminar. Here, Prof. Markku Lehtinen explains the major projects and the vital link between them.
The graphic on the slide was one from the early days of the web log. Still as relevant as ever! :-)

Installing the field equipment
This past week, a team from KAIRA/SGO, LTU and EISCAT have been installing a digital beamforming system on the Kiruna Demonstrator Array. Today, we feature some of the photographs from the installation of the field equipment.

Receiver/USRP installation on the Kiruna Demonstrator Array
This week a team from KAIRA/SGO and LTU, together with our colleagues from EISCAT, are working to install a digital beamforming system on the Kiruna Demonstrator Array. During the next week, we'll be featuring a few photographs from this busy time.

EISCAT 2013 underway
This week we are having the EISCAT International Symposium at Lancaster University in the United Kingdom. Today's photograph was taken by Thomas Ulich, who made this panorama of the participants just as the conference was getting started. Although it has been posted already on the E3D weblog, it is such a great shot that we asked it we could put it here too!
The speaker at that particular moment was Craig Heinselman (EISCAT Director) who was giving the introduction presentation.
You can follow the progress here on the EISCAT_3D web log, on the EISCAT_3D Facebook page, as well as on three different Twitter feeds: @EISCAT_3D, @EISCATUK and our own @KairaProject.

The Kiruna Demonstrator Array
As we wrote earlier, we went to Kiruna last week as part of the planning for the demonstrator array work. The Kiruna EISCAT Demonstrator Array is a phased array of 48 Yagi antennas, arranged in either a 4×12 grid or 4×6 grid... depending on he configuration. It operates at VHF frequencies and is capable of detecting signals from the VHF transmitter in Tromsø.The
demonstrator array was mainly built to be an experimental test bed for
the digital receivers and digital beam steering that was proposed in the
EISCAT_3D design study. Part of the work that the KAIRA team is carrying out is related to this work.

Random photos from Uppsala
Last week we had the EISCAT_3D users meeting in Uppsala, Sweden. It was a very successful meeting.. and not just because of the talks given on KAIRA!
We have a collection of photographs from various times and stages of the conference. And, although the conference photograph has already been posted on the EISCAT_3D web log, we felt we should share half-a-dozen or so (well, okay, 10 then) as a reminder of what was a very successful meeting.
Thanks to Mikko Orispää for submitting lots of excellent photographs too.
Enjoy!

E3D visit to the KAIRA site
Last week we hosted a small visit to the KAIRA site by some of the EISCAT_3D project team. The main objective was to show the site the new EISCAT director and explain the significance of our project and demonstrate its capabilities.

Aurora over the E3D meeting
During the EISCAT_3D "all-hands" meeting, we were treated to some mostly-clear skies and a bit of auroral activity too.

EISCAT 3D meeting in Kiruna
KAIRA is linked to the EISCAT_3D project. As a result, we are participating in this week's "All-Hands" meeting, which is being held at the Swedish Institute for Space Physics. This is where the EISCAT headquarters is also located. It is a great opportunity to get the team together to talk about the upcoming work in the project and to review the current situation.
The photograph shows Craig Heinselman talking about recent developments on another phased array radar system.
Craig will be taking over as Director of EISCAT in 2013. We all look forward to working with him.

EISCAT_3D Science Case
The second revision of the EISCAT_3D Science Case has been publicly announced via the EISCAT_3D website. This science case document was prepared as a part of the EISCAT_3D Preparatory Phase. It is updated regularly and is an excellent summary of the scientific goals. Obviously, apart from EISCAT_3D itself, much of this will impact on the work being done by KAIRA — both as a pathfinder for the EISCAT_3D project and as a stand-alone experiment.
