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).

In addition to the U.S. partners, the SuperDARN collaboration counts many international partner institutions that share an interest in studies of the ionosphere and the relationship between the ionosphere and space weather.

SuperDARN dissertation and thesis library now available

With the help of SuperDARN collaborators, Dr. Evan Thomas at Dartmouth College has rebuilt the list of student products that have drawn on or benefited from SuperDARN research activities. The list contains nearly 200 items and is sorted by author and year. Evan has posted the list to a publicly available Github repository: https://github.com/SuperDARN/theses_dissertations(external link)

The repository includes a few sample C programs to demonstrate parsing the thesis/dissertation text file and building html for displaying on a webpage.

In Evan's words: 'Thank you again to everyone who has contributed and please help me keep this resource up-to-date as your current and future students complete their degree programs.'

Upgrade to VT SuperDARN Data Server underway - service interruptions possible

By: miker  on: Fri., Nov. 01, 2019 12:00 PM EDT  (253 Reads)
October 31, 2019: Kevin Sterne notified the SuperDARN collaboration that the hard drive capability of the VT SuperDARN server is being expanded. In his words: '..for the next few days, data from 2019 may be limited via the VT website. My apologies for this inconvenience, but it comes with the advantage of being able to store many more years of data.For any immediate needs, you can e-mail me off list at .'

Notes on current VT Server:
We have a JetStor RAID 6 array by ACNC (http://www.acnc.com/) with 24 4 TB harddrives attached to a computer running Ubuntu 12.04 Server Linux. Because of the way RAID 6 and file systems work, this effectively gives us 77 TB worth of storage. The RAID array looks like a giant hard drive to our server.

Visiting scientists tour the site of the Blackstone radar

By: miker  on: Fri., Apr. 26, 2019 05:02 PM EDT  (1427 Reads)
On April 25 a group of visitors was led by Kevin Sterne to make a tour of the Blackstone SuperDARN radar. Drs. Nozomu Nishitani and Tomo Hori and graduate student Kento Oya from ISEE Nagoya University were joined by Dr. Erxiao Liu from Hangzhou Dianzi University. The photograph shows the Japanese visitors with Kevin and towers of the two arrays and the equipment shelter in the background.

Kapuskasing Aug. 2018 Trip

By: ksterne  on: Fri., Feb. 01, 2019 10:55 AM EST  (1691 Reads)
During the installation of the low loss coaxial cable in Oct. 2015, only the main array had new ground coax cable installed as time ran out to finish installing ground coax cables to the interferometer array. With a push from Simon Shepherd at Dartmouth College to get more radars collecting elevation angle, a trip to the Kapuskasing radar was planned for Kevin Sterne, Paul Kennedy, Mike Ruohoniemi and Simon Shepherd. In addition to installing the ground coax cables, the condition of the antennas along both array and the transmitters would be investigated and checked as the last service trip was the Oct. 2015 trip. Lastly, this trip was necessary to install signage around the site in order to comply with safety standards with the Canadian government.
