James Clemmons works in the field of space physics. His interests include auroral phenomena, physics of the Earth's ionosphere-thermosphere system, and the magnetosphere. Primary methods of inquiry are space experiments and instrumentation, as well as analysis of data. He serves as a Co-Investigator on NASA's Van Allen Probes and Magnetospheric Multiscale missions. Recent sounding rocket experiments include the Auroral Jet and RENU-2 missions, and current projects include the VISIONS-2, TOMEX-Plus, and Dynamo-2 sounding rocket missions, the LLITED cubesat mission, analysis of data from the TWINS-ES experiment, and modeling of the atmospheric mass density anomaly beneath the earth's magnetospheric cusp.
