Welcome to SuperDARN!
SuperDARN stands for Super Dual Auroral Radar Network. The network consists of over 30 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.

SuperDARN - An NSF Geospace Facility
The U.S. component of SuperDARN is funded by the National Science Foundation under the Geospace Facilities (GF) program as a collaboration between Virginia Tech (lead institution) and the Johns Hopkins University Applied Physics Laboratory (JHU/APL). The primary SuperDARN web site is hosted by JHU/APL. Supporting web sites are hosted by MSI/SuperDARN partners at Dartmouth College and University of Alaska Fairbanks. Click logos for access.




Hokkaido West Radar under Construction

PI Nozoumi Nishitani of the Solar-Terrestrial Environment Laboratory (STELab) in Nagoya is pleased to announce that the Hokkaido West radar is under construction. This will be the second SuperDARN radar on the northernmost Japanese island of Hokkaido and it will extend the coverage of the mid-latitude SuperDARN chain into northeast Asia. The site lies 1.1 km from the site of the first Hokkaido radar. The radar is expected to start operation later this year. Both Hokkaido radars are outfitted with electronics from the University of Leicester.

Stokkseyri radar transferred to new SuperDARN PI Jim Wild

By: miker  on: Mon., June 23, 2014 01:26 PM EDT  (182 Reads)
As announced at the 2014 SuperDARN Workshop held in Longyearbyen, Svalbard, the ownership of the Stokkseyri SuperDARN radar has been transferred from CNRS/LPCE (France) and PI Dr. Aurelie Marchaudon to Lancaster University (UK) and new SuperDARN PI Prof. James Wild. The Stokkseyri radar was constructed in 1994 as part of the first wave of radar construction under the newly-founded SuperDARN collaboration and its first PI was Dr. Jean-Paul Villain. It forms a common-volume pair with the Goose Bay SuperDARN radar.

Jim studied for a degree in Physics with Space Science and Technology before completing a doctorate in solar-terrestrial physics at the University of Leicester. He is the Professor of Space Physics at Lancaster University’s Department of Physics. He was elected to membership in the SuperDARN PI committee at the Svalbard Workshop.

Congratulations, Jim!

Meeting Dates: May 25-30, 2014
Deadlines for Registration & Accommodation: 23rd February 2014
Deadline for Abstracts: 25th April 2014
Deadline for Requesting Eduroam account: 15th May 2014 - Click 'Read More' for details
The 2014 SuperDARN meeting is going to be held in Longyearbyen, Svalbard (Norway). Longyearbyen is located on an archipelago at 78˚ North Latitude, making it one of the northernmost towns in the world. Longyearbyen has a long history of auroral and ionospheric research and is home to EISCAT Svalbard Incoherent Scatter Radar, the Kjell Henriksen Auroral Observatory, and the University Centre in Svalbard (UNIS). Longyearbyen is slated to be a future site of a SuperDARN radar.

Pictured: The 32 m dish of the EISCAT Svalbard radar (ESR). This radar operates in the 500 MHz band with a peak transmitter power of 1.0 MW. Foreground: Students from UNIS, the world's northernmost institution for higher education and research.

Fort Hays Trip, May 2014

By: ksterne  on: Thu., July 03, 2014 10:33 AM EDT  (214 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.

Blackstone Trips March/April 2014

By: ksterne  on: Tue., Apr. 15, 2014 04:01 PM EDT  (480 Reads)
After the overhaul of electronics at the Blackstone site in 2011, a better way of controlling the phase beam steering was introduced with a modified version of what the University of Saskatchewan radars are using (Saskatoon, Inuviuk, Prince George, Ranken Inlet, and Clyde River). This design makes use of direct digital synthesis (DDS) chips and a micro-controller to create the phase shifts as well as the control signals that are needed to run the radar. The modified design was purchased from the University of Saskatchewan and assembled in the Virginia Tech lab between 2013 and 2014. During the end of March and a separate trip on April 8th, the modified Univ. of Saskatchewan design was installed at the Blackstone radar. Also during these trips, measurements and calibrations were done in order to reconfirm the tdiff to be used in the hdw.dat.bks file.

In the end these calculations did not result in a new line to the hdw.dat.bks file from the previous change on July 9, 2013. As well, the Blackstone radar began recording elevation angle data late in the day on March 27th, 2014.
