Dear Colleagues,

We would like invite you to submit an abstract and participate in the session, “ST3.7/AS4.54 Study of the middle and upper atmosphere irregularities to identify forcing mechanisms” at the upcoming EGU General Assembly in Vienna, 7-12 April 2019.

The abstract submission deadline is 10 January 2019, 13:00 CET.

Session Description: 
The study of the ionized and neutral atmosphere reveals to be an efficient diagnostic tool to understand the interaction among the geospheres and the impact of the solar wind on the Earth. Any variation from the expected behaviour can be helpful to identify various forcing mechanisms originated from below and above. The vertical coupling in the atmosphere involves the influence of the upper atmospheric layers on climate and the response of the ionosphere to the modification of neutral atmosphere chemistry and dynamics. An exacerbation in the space weather conditions, in turn, can cause changes in the neutral composition and in the electron density structuring. In addition, natural hazards, such as tsunami, earthquakes, thunderstorms can produce atmospheric acoustic gravity waves that result in electron density perturbations in the ionosphere. 
The broad availability of instruments on board satellites and hosted at ground opens new opportunities of multi-disciplinary and multi-instruments collaboration to advance the current understanding in the field. 
This session welcomes observational, theoretical, and modeling contributions on atmospheric irregularities to identify the coupling mechanisms within the atmosphere, between the atmosphere and the lithosphere, and between the atmosphere and the geospace.

We are looking forward to receiving your abstracts and participation.

Kind regards,

Conveners:
Lucilla Alfonsi, Elvira Astafyeva, Naomi Maruyama, Jøran I. Moen

3. JOB OPENING: Post Doctoral Fellow – Magnetospheric Physics at Johns Hopkins University Applied Physics Laboratory
------------------------------------------------------------
From: Ian Cohen (Ian.Cohen at jhuapl.edu)

The Space Physics Group (SRP) of the Johns Hopkins University Applied Physics Laboratory Space Exploration Sector is conducting a search for a Post Doctoral Fellow in the Particles & Planetary Section. The Particles & Planetary Section research aims to understand the dynamics of planetary magnetospheres through novel instrument development, advanced modeling, and innovative data analysis methods. To this end, the Section conducts cutting-edge research in magnetospheric physics, with particular expertise in the dynamics of charged particles and energetic neutrals. The Section members possess considerable experience in advanced data analytics, modeling, instrument development, systems engineering, and project management. The Section scientists play science leadership roles in several ongoing and future space missions, including MMS, Juno, Cassini, JUICE, Europa Clipper, and IMAP.

The Postdoctoral Fellow will be involved in research of magnetospheric energetic particle dynamics using data primarily from the NASA Magnetospheric Multiscale (MMS) mission, presenting and publishing the research findings at international conferences and in the peer-reviewed journals, as well as participating and leading NASA and NSF grant proposals.

For further details please contact Ian Cohen (Ian.Cohen at jhuapl.edu) or Barry Mauk (Barry.Mauk at jhuapl.edu). Interested applicants can submit their applications online at the following link:

https://jhuapl.taleo.net/careersection/2/jobdetail.ftl?job=18704

Job Summary:
The research position focusses on MHD, extended MHD (e.g., multi-fluid and Hall MHD) and kinetic (test-particles) simulations representing plasma physics occurring in the magnetospheres of Earth and other planets. The research area includes the simulation of plasma processes in these environments and their analysis with the focus on the diagnosis of observable distinguishing signatures. The candidate will work in partnership with staff in the group with expertise in global MHD, particle tracing and particle-in-cell (PIC) simulations, kinetic plasma theory and data analysis. The successful candidate would be expected to publish original research in peer-reviewed journals and team with SRP staff to pursue external support for continued research and development for fundamental simulation research as well as projects relating to past, ongoing, and future missions.

Expected Duties:
1. Analyze and interpret data regarding the physics of planetary magnetospheres using particle and other data from orbiting spacecraft, present findings at scientific conferences and write scientific articles. Initially the focus will be on data from the MMS mission at Earth. (80%)
2. Participate in particle instrument operations during the science phases of spacecraft missions in the area of science planning, science planning trade studies, data processing oversight, and data display and tool development. Initially, the focus will be on the MMS mission. (10%)
3. Lead and/or assist with grant and project proposals to NASA and other funding agencies. (5%)
4. Participate with the development of space physics instrumentation (with an initial preference for those that measure charged particles) and eventually take the lead on developments of his/her own. (5%)  

Required Qualifications:
• PhD in Physics (or a related field) with research background applicable to space physics; or the demonstrated equivalent experience
• The applicant must have published first author scientific papers in a peer-reviewed journal and contributed to other scientific articles, must have a demonstrated ability to give quality scientific presentations, and demonstrated the skills necessary to write quality papers and grant proposals.

Desired Qualifications:
• The applicant should have in-depth knowledge of space plasma physics including acceleration transport and loss mechanisms of energetic and suprathermal particles in planetary magnetospheres.  
• The applicant should have a working knowledge of data display and analysis packages comparable to IDL (preferred), Python, Matlab, or equivalent. 
• Demonstrated understanding of the workings of space particle instruments, and ability to analyze their performances with computer algorithms and other tools.

Special Working Conditions: Travel to mission project meetings and to scientific meetings is required.

Benefits: APL offers a comprehensive benefits package including a liberal vacation plan, a matching retirement program, significant educational assistance, a scholarship tuition program for staff with dependents, and competitive salaries commensurate with skills and experience. For more information about our organization, please visit our web site at www.jhuapl.edu.

Equal Employment Opportunity: Johns Hopkins University/Applied Physics Laboratory (APL) is an Equal Opportunity/Affirmative Action employer that complies with Title IX of the Education Amendments Acts of 1972, as well as other applicable laws. All qualified applicants will receive consideration for employment without regard to race, color, religion, sexual orientation, gender identity, national origin, disability, or protected Veteran status.
