Welcome to SuperDARN!
SuperDARN stands for Super Dual Auroral Radar Network. The network consists of 35 low-power HF radars that look into Earth's upper atmosphere beginning at mid-latitudes and extending into the polar regions. The radars operate continuously and observe the motion of charged particles (plasma) in the ionosphere and other effects that provide scientists with information on Earth's space environment. The knowledge gained from this work provides insight into space weather hazards including radiation exposure for high-altitude travelers and disruptions to communication networks, navigation systems (GPS), and electrical power grids.

The SuperDARN Research Group at Virginia Tech (VT) collaborates with an international community of scientists and engineers to operate radars and share data. The VT Group operates five radars. For a summary of the radars and their affiliations, visit the Radar Maps/Tables/Links web page.

U.S. SuperDARN Collaboration
The U.S. component of SuperDARN is funded by the National Science Foundation under the Space Weather Research (SWR) Program as a collaboration between Virginia Tech (lead institution), Dartmouth College, University of Alaska Fairbanks (UAF), and the Johns Hopkins University Applied Physics Laboratory (JHU/APL).

Total Solar Eclipse to Sweep over Svalbard on March 20, 2015

By: miker  on: Tue., Jan. 13, 2015 02:27 PM EST  (689 Reads)
A total solar eclipse will take place on March 20. The path of totality will pass over Svalbard at 10:10 UT and sweep through the fields of view of multiple SuperDARN radars. Totality will last for 2 min 47 seconds. The accompanying plot shows the path of the eclipse with time stamps (credit: Muhammad Rafiq - VT).

Aurélie Marchaudon of IRAP/CNRS is making the arrangements to schedule SuperDARN radars to run in Discretionary Time (DT) for the period 20 March, 08 - 16 UT. One focus of the run will be to observe AGWs caused by the eclipse.

SuperDARN-Related Article Provides Cover Page for JGR October issue

By: miker  on: Thu., Dec. 04, 2014 02:40 PM EST  (422 Reads)
An article lead-authored by graduate student Christer van der Meeren of the Birkeland Centre for Space Science at the University of Bergen has been selected to provide the cover image for the October 2014 issue of the Journal of Geophysical Research - Space Physics. The article examines the occurrence of GPS scintillations and irregularities in relation to a tongue of enhanced ionization that extends into the nightside ionosphere at polar latitudes.

The cover image shows a sequence of maps of total electron content (TEC) obtained from GPS measurements with simultaneous convection patterns obtained from analysis of SuperDARN velocity data overlaid. The circle indicates the field of view of instrumentation located on on Svalbard.

Christer is advised by Prof. Kjellmar Oksavik. The figure was generated with the help of the on-line GPS/TEC plotting tools developed by graduate student Evan Thomas at Virginia Tech and collaborators at MIT Haystack Observatory.

VT Crew makes repairs to the Kapuskasing Radar

By: miker  on: Thu., Oct. 16, 2014 10:40 PM EDT  (585 Reads)
Kevin and Mike from Virginia Tech traveled to northern Ontario October 2 - 8 to visit the site of the Kapuskasing SuperDARN radar and make repairs. A number of technical issues were addressed including the performance of the interferometer array. By the conclusion of the trip all 15 available transmitters were functioning although a couple were out on receive owing to a lack of a needed spare part. The sensitivity of the radar has been significantly improved, in time for the first dark moon campaign period at the end of October. A slow internet connection continues to be worked on. This was the first meeting of the VT crew with the new site operator, Mr. Ghislain LeBouef. Ghislain participated in the repairs and arranged discussions with local vendors.

Fort Hays Trip, May 2014

By: ksterne  on: Thu., July 03, 2014 10:33 AM EDT  (1117 Reads)
In early April, the returns from the Fort Hays radars changed drastically. The problem began on April 4th with very noise signals being recorded on both radars. The original problem seemed to begin with a blown fuse in the PTS160 synthesizer. However, in the process of replacing the fuse, some of the connections on the back of the QNX6 computer must have come loose. In phone and e-mail conversations with Ryan White, FHSU SuperDARN intern, it seemed as though something was wrong with the RXFE or the way the RXFE was being controlled. In the end, it seemed as though a touchy connection between one of the outputs of the QNX6 computer and the control cable was causing the RXFE to not keep the correct settings. A replacement for this connection was put together and a trip was made to the site to repair this connection as well as do an assessment of the site.
