Job description

Purpose:

The main purpose of the job is to compute new diffusion matrices, taking into account co-located measurements of the wave and plasma parameters, for chorus and plasmaspheric hiss using data from THEMIS-A, THEMIS-D, THEMIS-E and Arase and to assess the role of these waves in radiation belt dynamics. The job will require frequent updates and presentations at team meetings and writing research papers in collaboration with other members of the SWA team.


Duties:

• Calculate new diffusion coefficients, taking into account co-located measurements of the wave and plasma parameters, for equatorial whistler mode chorus using wave, magnetometer and density data from the THEMIS-A, THEMIS-D and THEMIS-E satellite missions

• Calculate new diffusion coefficients, taking into account co-located measurements of the wave and plasma parameters, for mid-latitude plasmaspheric hiss and whistler mode chorus using wave, magnetometer and density data from the Arase satellite

• Investigate the roles of equatorial chorus at large radial distances and of plasmaspheric hiss and chorus at midlatitudes on radiation belt dynamics by comparing and contrasting the new diffusion coefficients with those using existing methods

• Incorporate the new diffusion coefficients from the THEMIS spacecraft and Arase with those from the Van Allen probes to create diffusion matrices for chorus and hiss throughout the radiation belts • Give presentations at monthly meetings and scientific conferences

• Write research papers in collaboration with other members of the team
