Opportunities exist in the Geospace Physics Laboratory of the Heliophysics Science Division to develop and validate magnetospheric stated-based trapped particle radiation models. In the past, the National Space Science Data Center (NSSDC) has developed two series of empirical radiation belt models (the NASA AE 1-8 and AP 1-8) based on spacecraft data from before the 1980s. Recent energetic particle data archived at the Space Physics Data Facility and elsewhere, up-to-date ionosphere models, and more realistic magnetic field models can be used to construct better radiation belt models that depend on geomagnetic conditions (e.g., to include dynamic effects). These models are important for radiation belt studies, spacecraft instrument design, space mission planning and operations, and for the reduction and analysis of high-energy astrophysical data sets. Anticipated work includes empirical and theoretical model development and validation, global magnetospheric simulations, as well as coordination and collaboration with other groups pursuing related efforts. In conjunction with the space radiation modeling, opportunities also exist in studying the physics of space radiation (sources, sink, acceleration, and transport) and the evolution of global magnetospheric states using a variety of data mining techniques to analyze magnetospheric state driver and response parameters, such as the measurements of solar wind, IMF, and geomagnetic indices.
