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

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).

Nathaniel Frissell successfully defends his doctoral dissertation

By: miker  on: Mon., Apr. 25, 2016 02:47 PM EDT  (81 Reads)
Virginia Tech SuperDARN student Nathaniel Frissell defended his doctoral disseration on Monday, April 25 to an examining committee of seven professors. Nathaniel is advised by Jo Baker and Mike Ruohoniemi. Nathaniel has published on the causes of Pi2 pulsations, the characteristics and sources of atmospheric gravity waves, and the role of citizen science in observating radio blackout during solar flares. He has contributed extensively to the web design and analysis tools found at the VT SuperDARN website. He has also participated in radar builds in Kansas and Alaska and in a trip to repair a radar located at McMurdo station, Antarctica. His defense was well-attended by family and friends including fellow radio hams. Nathaniel is moving on to a postdoctoral position at the New Jersey Institute of Technology (NJIT).

Congratulations, Nathaniel!

Van Allen Probes mission enters extended phase, MMS and ERG satellite missions on track

By: miker  on: Mon., Mar. 28, 2016 04:20 AM EDT  (214 Reads)
An EOS Buzz article by Sasha Ukhorskiy and colleagues at JHU/APL and NASA/GSFC summarizes the accomplishments of the Van Allen Probes prime mission and describes the science objectives of the extended mission (begun on November 1, 2015) and connections to the NASA MMS and JAXA ERG missions. Note that the sunspot number peaked in April 2014 and we are now in the declining phase of the solar cycle. See https://mail.google.com/mail/u/0/#inbox/153ad3d831ac2cf3(external link)
SuperDARN is running modes in support of the satellite missions as described in this earlier article: http://vt.superdarn.org/tiki-read_article.php?articleId=224(external link)

Dome C East radar in Antarctica returns to operation after successful trip

By: miker  on: Fri., Feb. 19, 2016 03:06 PM EST  (358 Reads)
News item from Maria Federica Marcucci: A power line failure at Dome C at the end of July 2015 brought down radar operations and subjected the equipment to -60C temperatures. David Biondi (INAF-IAPS) and Enrico Simeoli (CNR-Reti e Sistemi Informativi) have travelled to Dome C and brought the radar back to life. As of January 2, 2016 the radar is once again contributing to the SuperDARN data stream.

Congratulations, David and Enrico! (Pictured here at the site, David on the right)

Blackstone Trip, Jan. 2016

By: ksterne  on: Wed., Jan. 27, 2016 11:07 AM EST  (1230 Reads)
Shortly before the winter break, the internet connection to the radar site went down. Being patient since the availability of people to check on it would probably be low, the connection remained off over the two week winter break. However, our local contact was able to check on the connection for us and noted that the Power-over-Ethernet (PoE) power supply had melted and thus the internet connection was broken. The damage to the PoE unit and the RJ45 connector can be seen in the picture. In order to keep the linux computer’s hard drive from filling up, a trip to the radar site was made to restore the connection. In addition, this trip would be used to install the newly acquired and configured linux computer.

Blackstone Trip, Dec. 2015

With two visitors from the National Space Science Center (NSSC) in China visiting the Blacksburg lab for two weeks, a trip to the radar site was planned in order to show the visitors the operations and common testing of a working radar site. The visitors, Jiaojiao Zhang and Ailan Lan, as well as Muhammad Rafiq (VT doctoral candidate) and Kevin Sterne made a trip to the site in December. This trip would also serve as wrapping up some loose ends before the end of the year. These loose ends included reinstalling the SmartUPS that needed a new battery after it failed over the summer. Lastly, the Reverse Beacon Network receiver would be disassembled and taken back to the Blacksburg lab as the equipment had been setup on a temporary basis for testing at a radar site. The receiving antenna on top of a stack of antenna poles shortly before it was disassembled is seen in the picture.
