Shibaji Chakraborty successfully sat his PhD Preliminary Exam on Wednesday, November 13 before a committee of seven professors. Shibaji has authored and co-authored papers that focus on the impacts of solar flares on the ionosphere, in particular, the effects of the ionization enhancement that leads to shortwave fadeout (SWF). This is the fastest form of space weather felt by Earth with only an 8 min delay for propagation of enhanced X-ray and EUV radiation from the sun. Shibaji is currently developing a model that incorporates the physis and chemistry that are needed to account for HF absorption in the ionospheric D region during geomagnetic disturbances. He now passes into PhD Candidate status.

Congratulations, Shibaji!

As reported by the University of Scranton and the American Radio Relay League (ARRL), Virginia Tech alumnus Nathaniel Frissell has won a $1.3 million, 3-year National Science Foundation (NSF) grant to study weather effects in the ionosphere by leveraging a network of amateur radio stations as a Distributed Arrays of Small Instruments (DASI) project. Principal investigator Frissell will head a collaborative team that will develop ground-based space science observation instruments and software. His research effort will recruit multiple universities and radio amateurs to operate a network of personal space weather stations.

Nathaniel initiated his studies of space weather with amateur radio networks as a graduate student with the SuperDARN HF radar group at Virginia Tech where he graduated in 2016. Recently he has begun a faculty position at the University of Scranton after holding positions at the New Jersey Institute of Technology. The University of Scranton news item can be found at https://news.scranton.edu/articles/2019/11/news-faculty-nsfgrant-frissell.shtml(external link)

Congratulations to Nathaniel on this success from his advisors and colleagues at Virginia Tech!

SuperDARN dissertation and thesis library now available

By: miker  on: Mon., Nov. 04, 2019 12:44 PM EST  (373 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.'

Upgrade to VT SuperDARN Data Server underway - service interruptions possible

By: miker  on: Fri., Nov. 01, 2019 12:00 PM EDT  (443 Reads)
October 31, 2019: Kevin Sterne notified the SuperDARN collaboration that the hard drive capability of the VT SuperDARN server is being expanded. In his words: '..for the next few days, data from 2019 may be limited via the VT website. My apologies for this inconvenience, but it comes with the advantage of being able to store many more years of data.For any immediate needs, you can e-mail me off list at .'

Notes on current VT Server:
We have a JetStor RAID 6 array by ACNC (http://www.acnc.com/) with 24 4 TB harddrives attached to a computer running Ubuntu 12.04 Server Linux. Because of the way RAID 6 and file systems work, this effectively gives us 77 TB worth of storage. The RAID array looks like a giant hard drive to our server.

Space@VT doctoral graduate Dong Lin has pointed out that NCAR hosts a program that makes it possible for graduate students to visit for periods ranging from a few months to a full year. In the words of the program announcement: 'NCAR's Advanced Study Program's Graduate Student (GVP) Fellowship is an excellent way to spend time at NCAR and work on parts of your thesis, or final project equivalent, with guidance from NCAR scientists and engineers. The GVP also is an opportunity to develop research collaborations at NCAR and to participate in professional development workshops and seminars.' The website for the program is https://asp.ucar.edu/graduate-visitors/graduate-visitor-program(external link)
Dong, now an ASP Postdoctoral Fellow at High Altitude Observatory, has offered to answer questions about the program and further opportunities. The deadline to apply is October 31, 2019
