Diurnal Anisotropy during Solar Activity Cycle Twenty and Diffusion-Convention Model
Abstract
Underground muon telescope data obtained at Embudo and neutron monitor data obtained at Deep River are divided into two sets; one covers the ascending phase of the cycle (1965 - 70) and the other covers the descending phase (1971 - 76). The amplitude of diurnal anisotropy calculated from the data does not agree with the value predicted by the simplified version of the diffusion-convection model; the discrepancy is worse for neutron data.
