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).

NOAA DSCOVR satellite on its way to L1 libration point

The Deep Space Climate Observatory (DSCOVR) is scheduled to begin operations this summer giving early warning of solar storms. It was launched from Cape Canaveral on February 11, 2015. Essentially, it will replace the Advanced Composition Explorer (ACE) satellite (in operation at L1 since the late 1990s) with upgraded measurement capabilities.

An EOS Earth & Space Science News on-line article by Delores Knipp and Douglas Biesecker describes the mission:

Total Solar Eclipse to Sweep over Svalbard on March 20, 2015

By: miker  on: Thu., Mar. 19, 2015 02:27 PM EDT  (1191 Reads)
A total solar eclipse will take place on March 20. The path of totality will pass over Svalbard at 10:10 UT and sweep through the fields of view of multiple SuperDARN radars. Totality will last for 2 min 47 seconds. The accompanying plot shows the path of the eclipse with time stamps (credit: Muhammad Rafiq - VT).

Aurélie Marchaudon of IRAP/CNRS is making the arrangements to schedule SuperDARN radars to run in Discretionary Time (DT) for the period 20 March, 08 - 16 UT. One focus of the run will be to observe AGWs caused by the eclipse.

Quick trip to Blackstone to install transmitters

By: ksterne  on: Fri., Apr. 10, 2015 09:44 AM EDT  (95 Reads)
A quick day trip was made by Kevin Sterne and Deven Chheda on March 27th, 2015 in order to install some repaired transmitters and give a look at the site to see how things were going. This trip was originally planned after an extended network outage as well as a fear that one of the computers at the site had gone bad. However, in the days leading up to the trip the network connection as well as the issue with the computer were corrected. This left us with smaller but also important issues to complete during this trip. One of these was to install two of the four transmitters that were being worked on in the Blacksburg lab. These two had been repaired and were ready to be installed back at the site. As well, a range calibration was performed during this trip as it was noticed that sometime in mid-September, the radar's range appeared to be off. As well, this would be Deven's first trip to a SuperDARN site, so the operations and systems were explained to Deven.

Wallops Island Transmitter Overhaul - March 2015

By: ksterne  on: Fri., Apr. 10, 2015 09:12 AM EDT  (81 Reads)
Early in March 2015, Kevin Sterne and Mike Ruohoniemi of Virginia Tech and Drew Knuth and Ethan Miller of John Hopkins University's Applied Physics Lab met at the Wallops Island SuperDARN site to assess the electronics and the condition of the site. This trip would serve to prepare for a larger trip during the summer where more effort will be put into enabling elevation angle data to be collected by the radar. As well, this trip would take care of a few outstanding issues including a check of the transmitters and radar control electronics.
