>70 MeV proton fluxes in the year following solar activity extremes at POES altitude in the geographic coordinate, with L (1.2, 1.35, 2.0, and 4.0, in black) and H_min (100 km, 300 km, and 600 km, in red) isolines overlaid, and with the flux peaking area marked by the lines crossing at [50° W, 26° S]; Left panels: observations by POES; Middle panels: model calculations with g_b function; Right Panels: model calculations with g_h function.
