Description:
DEVELOPMENT OF A NEW GROUND-TO-SPACE ATMOSPHERIC PREDICTION MODEL

The Space Science Division of the US Naval Research Laboratory (NRL) in 
Washington, DC seeks a highly motivated individual to immediately join a 
cross-disciplinary multi-institutional research team, tasked with rapidly 
developing and validating a new state-of-the-art global numerical model of the 
neutral atmosphere extending from the ground to 400 km altitude, for high-
resolution forecasting of the deep atmosphere for terrestrial and space-
weather applications. The successful candidate will join a strong team of 
research scientists already in place at NRL and partner institutions that 
builds upon NRL’s institutional expertise in high-altitude atmospheric model 
development for new and improved operational environmental prediction 
capabilities for the globally deployed Navy.

The new atmospheric model is based on an emerging Navy dynamical core that 
solves the deep-atmosphere nonhydrostatic equations on the sphere using 
spectral element (SE) methods. The candidate will work primarily with a group 
at NRL DC developing and validating new upper-atmospheric (mesospheric and 
thermospheric) components of the model, including dynamics and physical 
parameterizations that respond to solar and geomagnetic forcings. The 
candidate will conduct high-resolution model experiments on massively parallel 
high-performance computers to test and validate new model physics and grids 
(e.g., static mesh refinement). In the process, the candidate may also 
collaborate with other project research teams located at NRL DC and elsewhere 
that are focusing on the model’s lower altitudes, high-altitude data 
assimilation capabilities, and physical coupling to ionospheric models. 

We seek a self-motivated candidate eager to study upper-atmospheric dynamics 
and physics relevant to short-term prediction, to develop efficient algorithms 
of these processes, to integrate them as new computer code within the evolving 
infrastructure of the new model, then to run and validate the new model in 
real-world whole-atmosphere scenarios. A Ph.D. in atmospheric science, 
computational fluid dynamics, physics, or a related discipline, is therefore 
preferred. Ability and willingness to work in the environment of a large, 
diverse and geographically distributed team, to achieve collective team goals 
and deliver specific monthly, quarterly and annual reporting milestones, are 
essential. Programming skills are required in working with a complex modern 
highly-scalable Fortran code using up to 1 million processors per run. 
Candidates with interests or expertise in applying modern coding practices on 
new and emerging supercomputing architectures are particularly encouraged to 
apply, though lack of expertise in such areas is not disqualifying. 

Interested U.S. citizens or permanent residents should directly contact Steve 
Eckermann (stephen.eckermann@nrl.navy.mil) with questions about the position. 
Applications will be accepted until 20 April 2021 or until the position is 
filled.  NRL is an equal opportunity employer.
