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. Click the logo below for access to the University of Saskatchewan SuperDARN site that features a real-time data display based on links to radars in North America.


Dr. Erxiao Liu of Hangzhou Dianzi University has been on an academic visit with the VT SuperDARN group for the past year. During this time he has worked on research related to the application of machine learning techniques to space science datasets, in particular to the estimation of the cross polar cap potential using SuperDARN data. He has made presentations and been an active participant in group meetings and activities. His wife Qiong Wang acclimated to life in Blacksburg and his daughter Zhenrui (Sherry) attended local school gaining remarkable proficiency in English. They enjoyed a boisterious (and victorious) Hokie home football game. The photo shows them decked out in Hokie gear on Erxiao's last day in the office; from left to right: Jo, Kevin, Erxiao, Sherry, Qiong, Mike, Bharat, and Shibaji. Erxiao and family now travel home in time for Chinese New Year. We wish them safe travels and much success !

Los Alamos Space Weather Summer School (June 1 - July 31 2020) - deadline extended to January 31

By: miker  on: Wed., Jan. 22, 2020 09:58 AM EST  (317 Reads)
The Los Alamos Space Weather Summer School is accepting applications for its 2020 session to be held June 1 - July 31, 2020. Sponsored by the Center for Space and Earth Sciences at Los Alamos National Laboratory (LANL), this summer school brings together top space science graduate students and LANL space scientists to work on challenging space weather research. Students receive a prestigious Vela Fellowship (worth $10,000 to cover travel and living expenses), technical training, and opportunities for professional development. Applications due: January 31, 2020 (extended deadline)

Eligibility: Open to U.S. and foreign graduate students currently enrolled in PhD programs in space physics, planetary science, aerospace engineering, or related fields. For more details see 'Read More' or the website http://swx-school.lanl.gov(external link)

Update to AACGM-v2 model now available from Dartmouth College

By: miker  on: Thu., Jan. 02, 2020 03:58 PM EST  (124 Reads)
Simon Shepherd has announced that the Altitude Adjusted Corrected Geomagnetic Coordinates (AACGM-v2) model, originally developed to compare conjugacy of data from SuperDARN radars in the northern and southern hemispheres Baker and Wing, 1989, has been updated. In his words:

'With the recent release of the 13th generation International Geomagnetic Reference Field (IGRF-13) (https://www.ngdc.noaa.gov/IAGA/vmod/igrf.html) an update to AACGM-v2 is now available at http://superdarn.thayer.dartmouth.edu/aacgm.html(external link)

The update includes new AACGM-v2 coefficients that extend the date range to 2025 and small changes to the software to accommodate the new date range and coefficient files.

Note that small differences in the IGRF-13 coefficients will cause corresponding small changes in AACGM-v2 coordinates derived using the new model for dates beginning in 2010.'

SuperDARN dissertation and thesis library now available

By: miker  on: Mon., Nov. 04, 2019 12:44 PM EST  (372 Reads)
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.'

PRIC Visitor Jianjun Liu makes working trip to the Blackstone radar

By: miker  on: Tue., Jan. 14, 2020 03:54 PM EST  (106 Reads)
Dr. Jianjun Liu from the Polar Research Institute of China (PRIC) made a working trip to the SuperDARN Blackstone site on January 13, 2020 and assisted in bringing this radar back on line. The crew included SuperDARN regulars Kevin Sterne and Mike Ruohoniemi and Virginia Tech undergrad Ian Kelley who performed significant diagnostics on the damaged parts. The PRIC is a member of the international SuperDARN collaboration (PI: Dr. Hongqiao Hu) and operates a SuperDARN radar at the Chinese Antarctic base at Zhongshan Station where Jianjun wintered over during a 14 month stay. He has been visiting the VT SuperDARN group since December and will return home later this week. The photo shows (from left to right) Jianjun, Kevin, and Mike standing in front of the Blackstone electronics.

Visiting scientists tour the site of the Blackstone radar

By: miker  on: Fri., Apr. 26, 2019 05:02 PM EDT  (1706 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.
