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.

Ice and wind bring down the towers of the Longyearbyen (Svalbard) SuperDARN radar

By: miker  on: Wed., Oct. 24, 2018 12:34 PM EDT  (204 Reads)
PI Dag Lorentzen has reported an unfortunate incident at the site of the Longyearbyen SuperDARN radar. In his words: 'All masts in both the main and interferometer array broke down due to high winds and ice loading. Although the antenna arrays have withstood two Svalbard winters, the current combined icing and wind conditions were enough to break the masts, most likely due to the heavy load of the fence and guy wires. The shipping container with the radar electronics is undamaged. With winter approaching we will unfortunately not be able to make any repairs, so the radar will most likely be out of commission for about 1 year.'

It was noted that the radar had been producing excellent data. The entire SuperDARN community hopes for a speedy recovery.

Blackstone Trip, July 2018

By: ksterne  on: Wed., Sep. 26, 2018 01:46 PM EDT  (313 Reads)
With the visit of FHSU student intern Kelly Strecker and with the repairs of some transmitters from the May 2018 trip, this trip to the Blackstone radar introduced Kelly to more radar hardware and allowed the installation of the transmitters. The goal with the transmitters was to get all of them firing as all of the antennas were repaired earlier in the year. With the two recently repaired transmitters, the radar was left running on all antennas at the end of this trip. However, two additional transmitters were found to not be running so these were brought back to the Blacksburg lab for repairs. These transmitters will be spares at the site once repaired and returned.

In addition to these items, a check of the electrical lengths along the coax and inside in the electronics was performed as gathering correct elevation angle data has become an emphasis across SuperDARN. The time delay was found to be close to previous values, with some small differences. This new difference will be reflected in the hdw.dat file for Blackstone.

Wallops Island Antenna Overhaul Trip Part I, May 2018

By: ksterne  on: Mon., July 02, 2018 02:56 PM EDT  (715 Reads)
After a trip in March 2018, the next steps in making repairs to the antenna array would be the removal of the old reflector wires as well as the upper and lower horizontal guy wires. A trip was made to the site in mid-May as the availability of personnel and a lift from Wallops Island’s facilities coincided at this time. Thanks needs to be given to Philip Smith with NASA/Wallops Island for coordinating a lift for us. A majority of materials ordered following the March 2018 trip would also be on hand by this time which would facilitate the initial steps needed for the repairs.
