Analytical Representations for Characterizing the Global Aviation Radiation Environment Based on Model and Measurement Databases.

The climatological model and the (ARMAS) statistical database are presented as polynomial fit equations. Using equations based on altitude, shell, and geomagnetic conditions an effective dose rate for any location from a galactic cosmic ray (GCR) environment can be calculated. A subset of the ARMAS database is represented by a second polynomial fit equation for the GCR plus probable relativistic energetic particle (REP; Van Allen belt REP) effective dose rates within a narrow band of shells with altitudinal and geomagnetic dependency.
