PL-GEOSPACE

Description:

PL-GEOSpace, a code that facilitates the assessment of space environmental hazards by bringing often-used environmental models together under the umbrella of a user-friendly graphics program. With the combination of three-dimensional visualization and access to a variety of models, PL-GEOSpace is an effective tool for magnetospheric and ionospheric research and education. Version 1.21 of PL-GEOSpace contains the CRRESRAD, CRRESPRO, and CRRESELE radiation belt models, an Auroral Precipitation Model, the Parameterized Ionospheric Model

(PIM), the WBMOD ionospheric scintillation model, and several internal and external B-field models. Application tools include orbit generation, flux/dose integration of the [CRRES models] along an orbit, and RF-HF ionospheric ray tracing. Output from the models and applications can be displayed many different ways as one, two, or three dimensional data sets. Orbit animation, a high resolution Earth model, and a celestial background are among the graphics features. Examples illustrating the construction of several specific magnetospheric and ionospheric environments with applications are

contained in the PL-GEOSpace User's Manual. Also included are the publicly available historical databases containing many of the geophysical parameters used by the models.
