Material for publicity and outreach is continuously produced in order to inform about the EISCAT_3D project. This material can be found here.
Basic information about the planned EISCAT_3D system, conveniently collected in the form of a small brochure.
The brochure can be downloaded here.
This brochure should be printed double-sided on A4 paper and then folded in three parts so that the heading “EISCAT_3D Europe's Next Generation Radar for Atmospheric and Geospace Science and images” is on the front, and the Time-Line and the contact information are on the back.
The EISCAT_3D Preparatory Phase project is featured in the June 2011 issue of International Innovation Environment Magazine. In the article, Esa Turunen and Jonny Johansson describe the project and its impact for near-Earth environmental science.
The article is available for download below, and the full magazine can be obtained through the publisher's website.
Tom Grydeland has made an attempt to visualise what a full-scale pan-Scandinavian EISCAT_3D instrument network should be able to do. His vision may serve as an inspiration in the work towards building the EISCAT_3D facilities. Tom participated in the EISCAT_3D Design Study and is currently working as a research scientist at Norut AS in Tromsø (department of Earth observation).
The network of real-time digital all-sky imagers awakes as the night falls, and their activity detectors start scanning the images for signs of auroral fine-structure. As the first substorm of the evening commences, the available narrow field-of-view cameras are directed towards the most promising auroral structures for imaging of the finer scales. EISCAT_3D is also connected to the network of all-sky imagers, and wherever the cameras have indications of structured phenomena, the closest radar diverts a broad illuminating beam for imaging towards the area. The precipitating particles in the aurora inevitably triggers instabilities, which manifests themselves as localized regions of very strong scattering, and the illuminating radar switches most of its transmitting power into the illumination of this structure, to obtain the best possible resolution in the imaging. Neighbouring transmitters shift some of their beams into the area usually covered by the closest radar, so as not to lose the background observations. Real-time coherence detection triggers the storage of massive amounts of raw data for imaging of the event, but only when the data contains scattering that can be imaged. The real-time imaging also ensures that enhanced scattering located differently than visible aurora is detected, and that events are recorded when the skies are not as clear as this night. Automatic SMS and MMS alerts are sent to key personnel, and to aurora hunters from the general audience who have subscribed to the automatic alerts. Plots and images are generated by the real-time system and appear on the web as the event progresses, and the fine-scale instruments (optical and radar) are continuously adjusting their look angles and fields of view to keep as much as possible of the event in view, and at the best possible resolution. At the peak of the event, when almost all of the sky is covered in aurora, all instruments concentrate on the local magentic zenith, where the opportunity to observe the finest scales is the greatest. The images from all of the all-sky imagers are combined to create a satellite's-eye view composite real-time true colour video of the entire northern Scandinavia, overlain with false-colour radar scattering maps, and the whole thing is broadcast across the web for anyone to see - in basic resolution for everyone, and in high definition to scientists and subscribers.
As the display draws to its conclusion, the fine-scale optical imagers go back to standby, the radars resume their synoptic modes, and broad illumination is only used for a few pulses per seconds in the event of something happening that the optical imagers cannot see.
Obviously, a single, relatively small deployment will not be able to do anything remotely similar to this. Even so, it is the necessary first step for such a vision ever to come true. The vision is what we keep in the back of our minds so as not to design ourselves into a too limited space, while experiences with a more limited deployment shows us what limitations we need to overcome and which problems we have to solve as our instruments evolve, step by step, in the direction of a grander vision.
Tom Grydeland earned the degree of Dr. Scient. (PhD) in 2003, on the topic of interferometric and high time-resolution observations of ionospheric plasma instabilities. He has also participated in the development of the MIDAS-W data acquisition and processing system at Millstone Hill, and worked on using electromagnetic methods for petroleum exploration for a few years before taking up his current position with Norut. He lives with his wife and children in Tromsø, Norway.
In the future, EISCAT will build the next generation incoherent scatter radar, which will provide comprehensive 3D monitoring of the atmosphere and ionosphere above Northern Fenno-Scandinavia. The EISCAT_3D radar system will consist of multiple phased arrays, using the latest digital signal processing to achieve ten times higher temporal and spatial resolution than the present radars.
A collection of videos for presenting EISCAT_3D.

A collection of pictures to present EISCAT_3D.
We have produced a collection of pictures showing how an EISCAT_3D array site may look when the system is completed. The art shows one of the possible designs designs of an active site - a site with both transmitting and receiving capabilities.
