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).

Vintage Radio Exhibition at Virginia Tech Library

By: Nathaniel Frissell  on: Tue., May 26, 2015 03:33 PM EDT  (5 Reads)
As part of the Wireless@VT 25th Anniversary Symposium, a vintage radio exhibition will be held at the Virginia Tech Newman Library on Wednesday, May 27, 2015 from 3 PM - 8 PM in the basement multipurpose room. This exhibit will feature radio equipment from early in the 20th Century through modern day. Radios on exhibit include vintage consumer radio receivers in wooden cases, early shortwave receiving equipment, amateur radio transceivers, morse code keys (and live demonstration station), vintage military radio, radios from the Motorola Museum, and a variety of cellular phones.

Many of the pieces for this exhibition have been made available by members of the Virginia Tech Amateur Radio Association (VTARA/K4KDJ) and may also be seen in this history video: https://www.youtube.com/watch?v=nbFgoGcQbcw(external link).

Discussion of Radar modes for the NASA MMS Satellite mission

By: miker  on: Sat., May 09, 2015 09:36 PM EDT  (702 Reads)
The NASA Magnetospheric Multiscale mission (MMS) launched as scheduled on March 12, 2015 at 10:44 EDT from Cape Canaveral carried by a United Launch Alliance Atlas 5 rocket.

Quoting from the NASA MMS website at http://mms.gsfc.nasa.gov/(external link) : 'The Magnetospheric Multiscale (MMS) mission is a Solar Terrestrial Probes mission comprising four identically instrumented spacecraft that will use Earth’s magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence.'

The science phase of the mission is scheduled to begin in September. SuperDARN is planning to operate in supporting modes.

NOAA DSCOVR satellite on its way to L1 libration point

By: miker  on: Fri., Mar. 27, 2015 10:33 AM EDT  (506 Reads)
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:

Quick trip to Blackstone to install transmitters

By: ksterne  on: Fri., Apr. 10, 2015 09:44 AM EDT  (421 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  (417 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.
