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).

Dr. Aurélie Marchaudon has announced that the “Planets, Environments and Space Plasmas” (PEPS) team of the Institute for Research in Astrophysics and Planetology (IRAP) of Toulouse (National Center for Scientific Research, CNRS and University Toulouse 3 - Paul Sabatier, UT3) will host the SuperDARN Workshop 2018 at the Oceanological Observatory of Banyuls-sur-Mer (Occitanie, France) from the 3rd to the 8th of June 2018. The website is open for late registration until May 27. Workshop website: https://superdarn2018.sciencesconf.org/?forward-action=index&forward-controller=index&lang=en(external link)

RST 4.1 release now available

Front Page News
A new version of the radar software toolkit (RST) has been released by the Data Analysis Working Group and can be found on the working group's github repository(external link) as version 4.1. Some major changes come with this new version including the deprecation of the '-new' flag in favor of using '-old' for data formats prior to 20060701 (*.dat, *.fit, etc.). The '-new' flag will no longer work and may break processing if used, so please update any external processing code.

In addition, RST 4.1 comes with major revisions to the gridding and mapping software. This means RST 4.1 will no longer produce the grdex and mapex files that are found on the VT-SuperDARN website. New files produced with the RST 4.1 code will be called grid2 and map2. These new files retain much of the same format as grdex and mapex files but are being separated to distinguish between the major revisions in the gridding and mapping software. RST 4.1 does maintain backwards compatibility so grdex and mapex files should be read and plotted with the current code.

Lastly, RST 4.1 introduces fitacf 3.0 as an experimental option of processing rawacf files into fitacf files. The default for this processing remains with fitacf 2.5, but users have the option to process what we at Virginia Tech are calling fitacf3 files with the command 'make_fit -fitacf-version 3.0'.

For now, grdex and mapex files will be produced to the end of 2017. Grid2 and map2 files will be produced starting with the beginning of 2017, but could be extended further back in time as necessary. Also, starting with the beginning of Dec. 2017, fitacf3 files will be produced in addition to fitacf (v2.5) files. Some of the web tools found on this website have been updated to plot this data. For the latest on what is available in the VT database, please refer to the data inventory page.

Blackstone Transmitter Repair Trip, April 2018

By: ksterne  on: Fri., Apr. 27, 2018 02:39 PM EDT  (229 Reads)
Following the March 2018 day trip to Blackstone, it was noticed that about 5 to 6 transmitters were not on or running for various reasons. As time did not allow of any kind of electronics checks during the previous trip, this trip was made by Kevin Sterne and Dr. Mike Ruohoniemi to review and make repairs on the electronics inside of the building. It was hoped that any outdoor work on the antennas could be performed during this trip, but logistics did not allow for making it worth renting a high-lift. In addition, the newly installed wireless hop system would be re-checked to see about improving the connection as it was still experiencing some minor problems despite staying up for the majority of the time.

Blackstone Wireless Hop Upgrade Trip, March 2018

Following an extended period of problems with the network connection to the site, a trip was planned after some new equipment was purchased to replace the aging wireless bridge system. The network connection has been a problem since the site was constructed, and in particular since the installation of new radios in 2011. However, through late 2017 and early 2018, the network connection was mostly down leading to long backlogs of data. To resolve this problem, new antennas, mounting hardware, and Ethernet cable were taken out to the site along with replacement radios that were in the lab. This trip was made while Mike and Kevin were coming back from Wallops Island in the two days prior. Of course, upon arriving to the site, the network connection was working.
