Job Description

What You Will DoLos Alamos National Laboratory is searching for a postdoctoral researcher to join the Space and Remote Sensing group (ISR-2). The Intelligence and Space Research Division at Los Alamos National Laboratory is inviting applications for a two-year position as a Postdoctoral Research Fellow.As a postdoctoral researcher, you will join a team working on Extreme D-Region Disruptions and VLF/HF/VHF Signal Impacts. The focus of this effort is to study and predict:Enhanced D-Region ionization driven from below by shocks and driven from above by radiation (electrons, solar protons, gamma rays). This work will utilize an existing LANL D-Region chemistry "laboratory" with five detailed schemes (LANL, DTRA, WACCM-D, UBAIM, CHARM), and will involve development of an emerging nested-grid ionospheric modeling capability based on SAMI3 with detailed chemistry.The impact of extreme D-Region disruptions on communications (VLF/HF) and lightning EMP propagation (VLF/VHF). This work will utilize an existing LANL full-wave code, built on an unstructured hexagonal grid (Voronoi tessellation), and will involve development of advanced ray tracing codes with associated predictions of Doppler and delay fading rates (spread) including modem impacts using an HF channel simulator (Watterson model).Assessment of observational measurements and validation studies will focus on high-latitude phenomena and may include ground- and space-based observations of ionospheric disruptions driven by HF heating at HAARP, riometer measurements of auroral events and polar cap absorption, GOES observations of solar energetic protons, and on-orbit measurements of VHF absorption from serendipitous arctic lightning using a unique LANL Radio Frequency Sensor (RFS) that will be launched this calendar year in geosynchronous orbit.What You NeedMinimum Job Requirements:Programming Skills: Strong programming skills, including familiarity with MPI and large computations on multiple cores, as well as experience with F90, R or Python and the ability to work in the Linux environment, are essential.Communication: Excellent oral, written and interpersonal communication skills.Work Ethic: Should be self-motivated, comfortable, and confident working independently.Education/Experience :A Ph.D. completed within the last five years in Physics, Mathematics, Atmospheric Science, Space Physics, Plasma Physics, Computational Chemistry, Radio Communications, or a closely related field is required.Desired Qualifications:Familiarity with ionospheric/atmospheric dynamics; upper atmospheric structures, plasma instabilities and variabilityUnderstanding of ionospheric radio propagation and communication modeling, especially for high-latitude disruptionsLocation: The position is physically located in Los Alamos, New Mexico.Where You Will WorkLocated in beautiful northern New Mexico, Los Alamos National Laboratory (LANL) is a multidisciplinary research institution engaged in strategic science on behalf of national security.
