Abstract
Cosmic ray (CR) anisotropy is one of main characteristics of galactic CR. We will show here that the observed CR anisotropy in the interplanetary space consists mainly from two parts with different origin and different dependence on particle rigidity. One part is produced by CR convection-diffusion processes and other part by drift processes . Both parts are connected with CR gradients and parameters of propagation of CR in space . Here we gave a short review on some statistical properties of 3-dimensional , North-South and ecliptic CR anisotropies in the Heliosphere , on determination by CR anisotropy data , transport parameters of CR propagation and distribution of gradients of CR density in the interplanetary space , on the separation of convection-diffusion and drift anisotropies and their properties in dependence of rigidity from few GV up to 330 GV found on the basis of CR observations for about 25 years by ground level neutron monitors and underground muon telescopes.
