EISCAT SOC is meeting in Tromsø, Norway

Currently, the EISCAT Scientific Oversight Committee (SOC) is meeting in Tromsø, Norway, hosted by Cesar La Hoz of the University of Tromsø. The meeting began on 29th March in the morning, and it will end by lunch today, 30th March 2012.

Of the many topics discussed in this meeting, the most prominent are:

  • The next International EISCAT Symposium will be held at Lancaster, UK, 12th-16th August 2013. Note that the name was changed from "workshop" to "symposium" in order to reflect the nature of the meeting better and to set it apart from the NSF AMISR Workshops, which, in fact, are radar schools.
  • The next International EISCAT Radar School will take place in Sodankylä, Finland, 26th August to 1st September 2012. The announcement will be published shortly.
  • Swedish Delegate Stephan Buchert, who is organising the EISCAT_3D User Meeting in Uppsala, Sweden, 23rd - 25th May 2012, pointed out that it is time to reserve accommodation in Uppsala soon, because hotels are often sold out very early in Uppsala. See also the announcement and the web site.
  • The deadline for submitting proposals for the EISCAT Peer-Review Programme is on 1st May 2012 (see here). Everyone, can submit proposals for using EISCAT radar time under this scheme, and we especially invite proposals from young scientists and non-EISCAT associate countries. However, also scientists from EISCAT associate countries are welcome to apply.
Participants in the SOC meetings (from left in the photo) are Wu Jun, Yasunobu Ogawa, Mike Rietveld, Erhan Kudeki, Mike Kosch, Cesar La Hoz, Ingemar Häggström, Thomas Ulich, Ingrid Mann, Alexander Koloskov, Stephan Buchert, Esa Turunen. Also present in yesterday's session were Asgeir Brekke, Unni-Pia Løvhaug, Tom Grydeland, and Magnar Johnson.

With best regards from Tromsø, we wish all of you a very good weekend!

Chapman Conference on Longitude and Hemispheric Dependence of Space Weather, Addis Ababa


The International AGU Chapman Conference on "Longitude and Hemispheric Dependence of Space Weather" will be held in Addis Ababa, Ethiopia, 12th to 16th November 2012. The conference will focus on two overarching themes:

A) How does the ionospheric response to major solar events depend on hemisphere and longitude; and

B) Expand the study of space weather to include day-to-day ionospheric variability, i.e., to those times when solar and geomagnetic activities are moderate and forcing from the lower atmosphere drives a lot of the variability.

The latter will include examining the cause of longitude and hemispheric dependence in total electron content (TEC) and occurrence of plasma density irregularities.

The conference will include six main science topics
  1. Hemispherical Dependence of Magnetospheric Energy Injection,
  2. Longitude and Hemispheric Dependence of Storm-Enhanced Densities (SED),
  3. Response to New Time-History of Solar Flares,
  4. Quiet-Time Longitude Spatial Structure,
  5. Temporal Response to the Lower-Atmosphere Disturbances, and
  6. Climatology of TEC and Scintillation in Different Longitude Sectors.

Further information will be available shortly.

Abstract deadline will be 12th July 2012.

Conveners:
Tim Fuller-Rowell (tim.fuller-rowell -at- noaa.gov), Patricia Doherty (patricia.doherty -at- bc.edu), and Endawoke Yizengaw (endawoke.kassie -a- bc.edu).

Resource: The "Cargèse Book" on-line

Today we want to draw your attention to an old publication, which is probably unknown to many, but very useful especially for those of you new to incoherent scatter radar experiments.

The EISCAT Technical Report 97/53: "Incoherent Scatter Theory, Practice and Science," is a collection of lectures given in Cargèse, Corsica, France in autumn 1995 before the 7th EISCAT Workshop at the same location. Denis Alcaydé served as the editor of this book, which was first published in print in 1997, and appeared in electronic form in 2001.

From the editorial: "This book is intended for use by graduate students for entering the field of Incoherent Scatter Research; it is felt however (and also hoped) that the various chapters of this book can be of some interest for more senior scientists. The book organisation is such that one can find at the beginning the main theoretical aspects of the Incoherent Scattering, followed by practical considerations on signal modulation, echoes and data analysis, and then scientific application aspects:
  • The first two chapters deal with the theoretical descriptions of scattering of plasma waves by the ionospheric plasma; Chapter one (Tor Hagfors) describes the "classical" Incoherent Scattering, while Chapter two (Wlodek Kofman) introduces the non thermal and instabilities effects.
  • In Chapter three (Asko Huuskonen and Markku Lehtinen) are introduced the basics of the modulation of the radio waves for pulsed radars. Once ionospheric echoes are received, some analysis can be made which lies upon some basic physics described in Chapter four (Kristian Schlegel).
  • The Solar Wind Magnetosphere interaction, Auroras and their ionospheric effects, Thermospheric Physics and the contributions made (or foreseen) by the Incoherent Scatter Observations are described in the following three Chapters (Chapter five, Mike Lockwood; Chapter six, Yoshuke Kamide and Chapter seven, Arthur Richmond, respectively).
  • The final Chapter (Chapter eight, Jürgen Röttger) deals with the theory, technique and science achieved with atmospheric backscatter and reflection processes of radio waves."
Most aspects of this book remain very much current, and you can download this valuable resource from the EISCAT web server. Note also, that many other EISCAT Technical Reports, so-called "Blue Books," are on-line, too.

Image: Cover of the EISCAT Technical Report 97/53, "Incoherent Scatter Theory, Practice and Science." The image shows a "incoherent scatter spectra computed with a typical EISCAT observation of the ionosphere in the ≈120-500 km altitude range. The spectral shape varies with the altitude as function of the observed electron temperature and of the ion temperature and composition. The spectral power is scaled to the electron density and the spectra are plotted along a line shape representing the altitude profile of the electron density."

An interesting week in Germany


This past week, the 13th Workshop on Technical and Scientific Aspects of MST Radar (MST-13) workshop took place in Kühlungsborn, Germany, at the coast of the Baltic Sea (19-23 March 2012). We heard news about all kinds of atmospheric radar, from wind profilers, meteor radars, MST radars, and also from incoherent scatter radars (Jicamarca, EISCAT). There's great interest in closer exchange between the atmospheric and ionospheric radar communities.

With this photo from the beach just outside the meeting venue, taken this morning, we wish all of you a nice weekend.

Report: EISCAT_3D Science Working Group meeting in Rome

The EISCAT_3D Science Working Group met at the Istituto Nazionale di Geofisica e Vulcanologica (INGV) in Rome on 12th and 13th January 2012. This was the first meeting of the group with the new membership for the second year of the study, focusing mainly on space weather. The members of the group for this year are: Anita Aikio (University of Oulu, Finland, co-chair); Ian McCrea (STFC Rutherford Appleton Lab, UK, co-chair); Lucilla Alfonsi (INGV, Italy); Herve Lamy (BIRA/BISA, Belgium); Frederic Pitout (Univ. Paul Sabatier, Toulouse, France); Iwona Stanislawska, (Space Research Centre, Warsaw, Poland) and Juha Vierinen (Sodankylä Geophysical Observatory, Finland).

During the first day of the meeting, each member of the group gave a presentation about their work and their ideas for the science areas to be addressed by EISCAT_3D. After each talk, there was discussion of the issues raised, and their possible implications for the design and science goals of the new radar. In addition, some new studies which would be possible with the present EISCAT system were identified. On the second day, the meeting split into two groups. One group discussed how to revise the space weather section of the Science Case. The second group discussed changes that should be made to other sections of the document. The results of this meeting will be new sections of the Science Case, which will be presented at the EISCAT_3D User Meeting 2012, to be held in Uppsala from 22nd to 25th May 2012.

Call for Papers: AOGS2012: Space Weather and Space Climate, Singapore

The Asia Oceania Geosciences Society (AOGS) and the American Geophysical Union (AGU) will hold a Joint Assembly in Singapore, 13th to 17th August 2012. The conference will include session ST22 on

Space Weather and Space Climate: Coupling Processes from the Sun to the Earth

The Sun, its extended corona, the interplanetary space, the Earth's magnetosphere, ionosphere, middle and low atmosphere, are all parts of a complex system – the heliosphere. Various manifestations of solar activity cause disturbances known as space weather effects in the interplanetary space, near-Earth environment, and all the Earth's "spheres." Long-term variations in the frequency, intensity and relative importance of the manifestations of solar activity are due to the slow changes in the output of the solar dynamo, and they define space climate. Space climate governs long-term variations in geomagnetic activity and is the primary natural driver of terrestrial climate. To understand how the variable solar activity affects the Earth's environment, geomagnetic activity and the atmospheric system on both short and long time scales, we need to understand the origins of solar activity itself and its different manifestations, as well as the sequence of coupling processes linking various parts of the system. This session provides a forum to discuss the chain of processes and relations from the Sun to the Earth's surface: the origin and long-term and short-term evolution of solar activity, initiation and temporal variations in solar flares, CMEs, coronal holes, the solar wind and its interaction with the terrestrial magnetosphere, the ionosphere and its connection to the neutral dominated regions below and the plasma dominated regions above, the stratosphere, its variations due to the changing solar activity and its interactions with the underlying troposphere, and the mechanisms of solar influences on the lower atmosphere on different time-scales. Particularly welcome are papers highlighting the coupling processes between the different domains in this complex system.

Abstracts due 12th March 2012 extended to 21st March 2012 at http://www.asiaoceania.org/aogs2012.

Main Convener Dr Katya Georgieva (Bulgarian Academy of Sciences, Bulgaria); Co-conveners Dr Nat Gopalswamy (GSFC, NASA, United States), Dr Georgeta Maris (Institute of Geodynamics of the Romanian Academy, Romania), Dr Boian Kirov (Bulgarian Academy of Sciences Sofia, Bulgaria), Prof. Ramon Lopez (University of Texas at Arlington, United States), Prof. Thai Lan Hoang (Vietnam Academy of Science and Technology, Viet Nam).

Radar School: Incoherent Scatter Radar School in Banff, Canada

Our American colleagues will organise the next Incoherent Scatter Radar Student Workshop at Banff Centre, Banff, Canada, from 29th July to 5th August 2012.

A workshop aimed at providing students with hands-on experience in designing and running experiments at incoherent scatter radar facilities will be held at the Banff Centre, Banff, Alberta, Canada. The workshop is being held in Canada for the first time in celebration of the brand new southward-looking Canadian Resolute Incoherent Scatter Radar (RISR-C). During this workshop, students will have the opportunity to run experiments and use data from multiple incoherent scatter radar observatories, such as Poker Flat (PFISR), Millstone Hill, Resolute Bay (RISR), Sondrestrom, Jicamarca and Arecibo. This is the fifth student workshop organised with the aim of teaching the new generation of scientists how to request and analyze incoherent scatter radar (ISR) experiments. All students will have the opportunity to work one-on-one with experienced scientists. The workshop will be structured to provide presentations in the morning, and hands-on experience in experiment design and analysis in the afternoons. The morning lectures will include an introduction to the theory of incoherent scatter, radar operations, ISR analysis techniques, and the Madrigal data base. The afternoon exercises will involve working closely with ISR facility staff in the topic areas of: proposal design, experiment execution, and data analysis.

This workshop is suitable for graduate and advanced undergraduate students. It is sponsored by the US National Science Foundation (NSF) through its Geospace Facilities Program within the Geosciences Directorate and hosted in partnership with the Canadian RISR-C team.

Attendance is limited to 30 students. For most students within the U.S. and Canada, travel, housing and meals will be provided. For post-docs and students outside of the U.S. and Canada, funding will be considered on a case-by-case basis. Providing there is space, professors and other professionals are welcome to observe. Please contact Anthea Coster (ajc -at- haystack.mit.edu) if you are interested in this option.

The deadline for application submission is 15 March 2012. Please see the ISR Student Workshop's Website for more information.
