Call for Papers: HEPPA-SOLARIS 2012

The 4th International HEPPA Workshop (High-Energy Particle Precipitation in the Atmosphere) will take place in conjunction with the SOLARIS (Solar Influences on SPARC, Stratospheric Processes and their Role in Climate), from 9th to 12th October 2012, at the National Center for Atmospheric Research, Boulder, Colorado, USA.

From the organisers: "Please join us for a four-day workshop focused on observational and modeling studies of the influences of solar radiation and energetic particle precipitation (EPP) on the atmosphere and climate. The meeting will last four full days, beginning Tuesday morning, 9 October. Broad topics to be covered include the causes and phenomenology of solar radiation and energetic particle variability, mechanisms by which radiative and particle forcing affect atmospheric chemistry and dynamics, contributions of solar and EPP forcing to climate variability and space weather, and the current state of the art and outlook for relevant observations and models."

"Format: Because of the interdisciplinary nature of this workshop, there will be several plenary sessions during which invited tutorials and overview talks will be geared toward the general audience. All contributed presentations will be given in the form of posters, for which individual, sequential sessions will be scheduled. All contributors will be given the opportunity to present a one-slide summary of their posters in the oral plenary sessions. Lively discussions will be encouraged, with abundant time for collegial interactions during poster sessions. The last day of the meeting will be reserved for the HEPPA and SOLARIS model/measurement inter-comparison working groups, which are open to all interested participants."

Please refer to the meeting web pages for more information.

Registration and abstract deadline is 17th August 2012.

International EISCAT Radar School, Sodankylä, Finland

In the near future the EISCAT Scientific Association will face a major instrumental upgrade with the ESFRI Roadmap project "EISCAT_3D: A European Three-Dimensional Imaging Radar for Atmospheric and Geospace Research."

EISCAT, in co-operation with the Sodankylä Geophysical Observatory (SGO), will run a training course for new users of the EISCAT radars, from 27th August to 1st September, 2012 (Monday to Saturday). The training course will be held at Sodankylä, where one of the EISCAT UHF remote sites is located.

The course will cover all essential aspects of the current EISCAT systems, including their science programme. An overview of the existing hardware and software will be provided and future plans will be discussed, with a strong emphasis on EISCAT_3D. Tips on analysing and working with the data will be given and the participants will run an own radar experiment in a hand-on exercise.

The lecturers comprise members of the EISCAT staff and experienced scientists from the user community. As well as providing a good foundation for new EISCAT users, the course will also provide a chance for more established users to be updated on the latest and future developments.

The deadline for registration in the course is 26th June, 2012.

EISCAT_3D User Meeting - Day 3

The EISCAT_3D User Meeting has come to a close. Sorry for the lack of updates today, but for some reason the wireless network at Ångström Lab became unavailable during the final session this morning. As mentioned, please check the meeting programme as well as the collection of presentations on-line. The latter will be updated when more contributions become available, most are there already.

Note that the next EISCAT_3D User Meeting will take place 6th to 8th May 2013, at Ångström Lab, Uppsala, Sweden. A big "Thank You!" goes to Stephan Buchert for arranging the past four User Meetings, and for being ready to host us again next year.

While you are marking this meeting in your diary, please also mark the also the International EISCAT Symposium (formerly "Workshop"), which will take place 12th to 16th August 2013 at Lancaster University, UK, kindly hosted by Mike Kosch.

Now, you might be wondering what all this has to do with the photo above. It's Friday, and that means it's time for an image feature. It's also spring time in EISCAT-land, and the snow is melting very rapidly. Just before leaving for Uppsala, this photo was taken at the shore of Kitinen and shows the oldest building of the Sodankylä Geophysical Observatory, the sauna on the shore, completely surrounded by water. With the snow gone, we are looking forward to resuming the construction of KAIRA and all kinds of other developments of EISCAT_3D.

With this we wish all of you a very good weekend!

EISCAT_3D User Meeting - Day 2

Today was the second day of this year's EISCAT_3D User Meeting, with many good and interesting presentations covering a large range of applications. You can find the programme of the meeting on-line, and also most, if not all of the presentations will eventually be made available on the EISCAT_3D project web site. During the day, proceedings were broadcast live on the EISCAT_3D Twitter feed, which one can follow even without having to register a Twitter account.

Altogether there have been three talks discussing the connections between LOFAR and EISCAT_3D. LOFAR is a large radio astronomy receiver array, whose operational frequencies cover the anticipated EISCAT_3D frequency of 233 MHz. Richard Fallows, who is now with ASTRON, showed results of simultaneous Interplanetary Scintillation measurements from pairs of LOFAR sites and from the EISCAT UHF sites at Kiruna and Sodankylä. The solar wind velocities obtained from all site-pairs agree to within about 1%!

Juha Vierinen, of SGO/U Oulu, discussed the plans for KAIRA, which is the Kilpisjärvi Atmospheric Imaging Receiver Array. KAIRA is built using LOFAR receiver hardware in order to do EISCAT_3D prototyping by receiving signals from the EISCAT VHF radar about 85 km away in Tromsø. Juha Vierinen was happy to tell that the "snow removal by wind" worked very well during the past winter, which is due to the HBA tiles being deployed on platforms as seen in the photo. The High-Band Array (HBA) has been deployed in 2011, but without the summators, which are taking care of per-tile beam-forming. These will be installed in week 23, so that test measurements can begin. Furthermore, the colleagues from Sodankylä will deploy a 48-antenna LBA array this summer at Kilpisjärvi, which will have a large number of applications including, e.g., use as imaging multi-frequency riometer.

In the afternoon, we heard reports from supporting actions in Norway and Sweden from Cesar La Hoz and Jörg Gumbel, respectively. The good news is that in the Nordic Countries, significant funds are being earmarked for infrastructure development, potentially large parts of which could go to EISCAT_3D. However, it was made very clear, that these funds will be made available through competitive, national application processes and decisions will be made on the basis of scientific merit. Deadlines for application are different from country to country, and the closest is already in October 2012 in Norway, i.e. in only five months time!

Later on, EISCAT Director Esa Turunen introduced the meeting participants to the EISCAT_3D site selection process. He showed maps computed by Mikko Orispää using a software by Ilkka Virtanen. This software allows for comprehensive modelling of EISCAT_3D based upon given parameters such as beam width, transmit power, number of aerials, number of remote sites, location of remote sites and many more. He reported that four possible sites have been surveyed as part of the FP6 Design Study, and a number of further sites were surveyed in 2011. Four or so more sites will be surveyed in the summer ahead. At the moment, the current view is that the central EISCAT_3D site will be within a 50-km circle around the location where the national borders of Norway, Finland, and Sweden meet. Effectively it seems likely that the central site might be placed between Skibotn and Kilpisjärvi.

Finally, the newly appointed EISCAT_3D Technical Expert, Björn Gustavsson, introduced the current status of the performance specification to the audience. While a lot of this is still under discussion, some key components were mentioned. The facility is likely to comprise a core site with three to six remote sites. At this stage it is not excluded that some of these might be active, too, or are at least upgradable. The centre frequency is anticipated to be near 233 MHz and the transmitter peak power should be ≈10 MW. There'll be several outlier antenna groups around the central site for in-beam interferometry (note, these will be much closer than the remote sites). The radar should have arbitrary phase, power and polarisation. Various layouts of aerials within one site as well as layouts of central and remote sites are being investigated.

There was a discussion on the advantages and disadvantages of having a central site, which is a combined transmit/receive site as opposed to what is called a "locally bistatic" site, i.e. a site that consist of distinct transmit and receive arrays. Markku Lehtinen (SGO/U Oulu), who could not attend the meeting, had sent some slides showing a back-of-the-envelope estimate, which indicated, that separated transmitter and receiver might well be advantageous and deliver a better performance given the same budget. This is because transmitter antennae need to function well only over a narrow frequency bandwidth while receiver antennae need to perform well over a much larger bandwidth in order to measure plasma lines. On the other hand, the transmitter antennae need to be sturdier than the receiver aerials. Due to separation of transmitter and receiver, a transmit-receive switch won't be necessary. All of this needs further investigations of the trade-offs performance-wise as well as financially.

During the discussion session, which concluded the day, Esa Turunen asked the audience whether anything crucial was overlooked, and, since EISCAT_3D will first of all be a science facility, is there something, that needs to be made possible, but hasn't been accommodated so far. Thus now it is time to get in touch and send your comments!

Automated Multi Dataset Analysis - AMDA

This morning, the scientists at the 4th EISCAT_3D User Meeting in Uppsala, Sweden, heard a presentation by Frédérik Pitout on AMDA, which is an on-line tool for "integrated multi-point/multi-instrument" data analysis.  This tool makes it easy to compare data sets of different origin. From the AMDA web site:

"The plasma objects studied in space physics consist of gigantic systems characterised by multiscale dynamics and fast long range couplings between key regions. For studying such systems, it is necessary to perform integrated multi-point/multi-instrument analysis in case studies and statistical studies as well. The ISTP program, the CLUSTER, THEMIS and MMS missions have been defined for facing this requirement. [...]

"Depending on the heterogeneity of the data and the dispersion of their sources, the scientists can spend a lot of energy and time just for searching, finding, treating and preparing the data before starting scientific analysis. In order to help the users to faster reach the data analysis and interpretation step, the CDPP is developing" the AMDA service. CDPP is the Centre de Données de Physique des Plasmas (Plasma Physics Data Centre).

EISCAT and Space Situational Awareness

At the 4th EISCAT_3D User Meeting in Uppsala, we have heard an interesting talk by Hannu Koskinen (U Helsinki) on the Space Situational Awareness (SSA) programme of the European Space Agency (ESA). includes four elements, which are Space Surveillance and Tracking (SST), Near-Earth Objects (NEO), Space Weather (SWE), and Data Centres (DC). SSA is a service-oriented programme, not a research programme.

Space surveillance radars exist already, and most are military facilities. Now new facilities are planned, with a monostatic radar in Spain and a bistatic system in France. While monitoring satellites is important, space debris has become a threat to space exploration, and space agencies are increasingly aware that space debris objects and their distribution needs to be monitored. One of the practical problems is that access to military space surveillance data is complicated.

Within the Space Weather element, four expert groups are proposed on Solar Weather, Ionospheric Weather, Radiation Environment, and Geomagnetic Environment.

What could be EISCAT's contribution to SSA? — The observation of small space debris particles has already been part of EISCAT's operations and it is anticipated that the new EISCAT_3D radar will very well be able to compete — or better: complement — other space debris monitoring systems. EISCAT will be very beneficial to space weather if one ensures, that experiments can be scheduled flexibly to react quickly to event alerts and warnings, and forward the observations immediately and efficiently to space weather partners.

Hannu Koskinen pointed out that the life-time of current solar wind missions is limited (ACE, WIND), and the upcoming KuaFu mission, which is a joint proposal of China, Canada and Europe, will be well placed to fill this function. The plan is to launch three satellites, one of which will be located at the L1 point, i.e. the place where the gravity of Earth and Sun balance out, which then will monitor events like solar flares and solar wind shock waves.

Executive Board Meeting, Arlanda (Stockholm)

The Executive Board (EB) of the EISCAT_3D Preparatory Phase Project met during the past two days at Arlanda, which is the main airport of Stockholm. Arlanda is a convenient location, because all but one participant can get there with one direct flight only. The Executive Board meets every three months, and in between the members keep in touch with telephone conferences every Friday afternoon.

Contrary to the situation in Sodankylä on Wednesday, at Arlanda spring is in full swing, the these flowers show, which are planted just outside our meeting hotel. But there's also a different view to the case of spring: in the North, when we talk about spring, we often refer to the time of March and April, when the days are getting longer, the weather is often sunny with the temperatures more and more frequently above freezing during the day, and solidly below freezing in the night. This is the best time for winter sports, since the thick snow cover will become very hard and it is easy to move everywhere, on skies, snow shoes, snow mobile, dog sled, or whichever way you prefer.

During this past meeting, which took place on 3rd and 4th May 2012, we discussed the progress of the EISCAT_3D project over the first reporting period of 18 months, which just ended in March 2012. This is a busy and important time, since full documentation of the project has to be submitted to the European Commission, which funds FP7 projects, within about two months after completion of this period.

At the beginning of this meeting, we were happy to welcome a new member to the team: Dr Björn Gustavsson joined the project on 1st May 2012. More about this in another blog post soon.

Have a good weekend, and enjoy the spring!
