Dependencies of CR cutoff rigidities from the altitude during 1950 - 2050 for different latitude - longitude zones and zones over great magnetic anomalies
Abstract
By using information on secular variations of Gauss coefficients of main geomagnetic field during 1950-2050 and Tsyganenko model on the changing of magnetospheric current systems during different levels of geomagnetic activity we determine by direct trajectory calculations space-time distribution of CR effective cutoff rigidity Rc. On the basis of these results we then determine how Rc depends from altitude H for different latitude - longitude zones and special zones with great influence of planetary magnetic anomalies. For convenient using this information for estimation level of radiation hazards from galactic and solar CR for satellites on different orbits at different moments of time we try to approximate the found dependencies of Rc from H by some analytical functions.
