Fig. 3From: Interplanetary particle transport simulation for warning system for aviation exposure to solar energetic particlesPitch angle distribution of near-Earth SEPs for radial mean free paths of 0.2 (top) and 1.4 AU (bottom). The distributions are shown at 1 (black), 3 (red), 6 (green), and 12 (blue) h after particle injection near the SunBack to article page
