(1) DMSP ABI midnight equatorward boundary on-line from 82363 to 13289.


From Barbara Emery (emery at ucar.edu).

The Air Force Research Laboratory (AFRL) devised the Auroral Boundary Index (ABI) from DMSP satellites. The ABI is an estimate of the auroral equatorward boundary at magnetic midnight at the NH magnetic latitude from the SSJ4 and SSJ5 instruments that measure electron and ion particle precipitation. A full description is at http://cedarweb.hao.ucar.edu/wiki/index.php/DMSP:ssj4_midnit along with references. Previously, only the estimate of the NH magnetic latitude was available at the UT of the actual equatorward auroral crossing at some magnetic local time (MLT). Now, that MLT is listed, along with the actual (mlat,mlon) and (glat,glon) of the crossing for the particular DMSP satellite. Since the ABI is estimated from the Kp index, a pseudo-Kp or provisional Kp, pKp, is also listed along with a quality flag based on how well the pKp in that particular satellite bin of (MLT,glon,season,hemisphere) was within 1.5 sigma of the real Kp in 27 consecutive crossings.

The new data files are available on-line from 82363 to 13289 in the CEDAR and the CEDAR Archival Madrigal Databases at:

(2) Jicamarca International Research Experience Program (JIREP) student applications due 24 Jan.

Student Research Opportunity in Peru over the summer at the Jicamarca Radio Observatory (JRO)

The students will work with staff engineers and scientists on projects related to ongoing research or instrumentation development programs. Research may be conducted in neutral atmospheric and ionospheric science as well as radar/radio instrumentation and software development. Given its location, frequency of operation, and array system, most JRO's research capabilities are unique. Besides the unique research capabilities where students are welcomed to propose and run their own experiments, JRO offers a good opportunity to get hands-on-experience on different aspects of radar systems, from changing the antenna connections, improving RF components of the system, to develop sophisticated acquisition and processing programs.

A side benefit of the program is that students will get to know Peru, heir to ancient cultures and rich colonial tradition. This program is offered to junior/senior undergraduate and/or first and second year graduate students and will cover the travel expenses (to and from Lima), as well as a reasonable stipend. Given that the Observatory is located outside Lima city, transportation will be provided.

  • Application deadline: January 24, 2014
  • Decision: February 20, 2014
  • Starting date: Anytime between May 12 until June 20, 2014
  • Duration: 10 weeks
