Improved COsmic Ray Ionization Model for Atmosphere and Ionosphere (CORIMIA) with account of Monte Carlo simulations

Abstract

The COsmic Ray Ionization Model for Ionosphere and Atmosphere (CORIMIA) is physical space weather model with fully operational implementations. CORIMIA produce values of electron production for different altitudes (30-120 km), solar activities (low, moderate and high), geomagnetic and atmospheric cut offs. CORIMIA can determine the energy intervals contributions for all groups of CR nuclei. The effects of galactic cosmic rays (GCR), solar cosmic rays (SCR) and anomalous cosmic rays (ACR) in the middle atmosphere are computed. The structure of the proposed model allows its decomposition in several submodels. Each submodel is further decomposed in submodels with account to the different characteristic ionization losses energy intervals. The ionization losses function is calculated taking into account the energetic particles charge decrease interval. The energy intervals investigation takes place according to the goal of the user of the model with respect to accuracy and interval types. CORIMIA program is applicable for the ionosphere and atmosphere above 30 km. Below this altitude numerical model such as CORSIKA are applied. At present the composite CORIMIA-CORSIKA programs are used.
