The travelling substance path in the charge reduction interval is evaluated and used for the calculation of the corresponding atmospheric transformation of the lower energy boundary, i.e.…”

“…CRs introduce solar variability in the middle atmosphere and ozonosphere-because they are modulated by solar wind. As a continuation of our studies of CR ionization in the atmospheres of the planets in the solar system (Velinov et al, 2001;Velinov et al, 2004), we will present an improved method for the calculation of the electron production rate q(h) profiles due to particles of all energy intervals: galactic CRs, anomalous CR component and other types of high-energy particles. The proposed improved CR ionization model will contribute to the quantitative understanding of solar-atmosphere relationships.…”

A brief review of the study during COST Action ES0803 of effects due to cosmic rays (CR) and solar energetic particles (SEP) in the ionosphere and atmosphere is presented. Models CORIMIA (COsmic Ray Ionization Model for Ionosphere and Atmosphere) and application of CORSIKA (COsmic Ray SImulations for KAscade) code are considered. They are capable to compute the cosmic ray ionization profiles at a given location, time, solar and geomagnetic activity. Intercomparison of the models, as well as comparison with direct measurements of the atmospheric ionization, validates their applicability for the entire atmosphere and for the different levels of the solar activity. The effects of CR and SEP can be very strong locally in the polar cap regions, affecting the physical-chemical and electrical properties of the ionosphere and atmosphere. Contributions here were also made by the anomalous CR, whose ionization is significant at high geomagnetic latitudes (above 65°-70°). Several recent achievements and application of CR ionization models are briefly presented. This work is the output from the SG 1.1 of the COST ES0803 action (2008)(2009)(2010)(2011)(2012) and the emphasis is given on the progress achieved by European scientists involved in this collaboration.

Abstract.A 3-D planetary model of the cosmic ray electron production rate q(h) (cm −3 s −1 ) has been developed for the strato-mesosphere and lower thermosphere (altitude range 30-100 km) with a 10-km step. The spectrum of the primary cosmic rays is modelled by an analytical expression using input data from the CREME96 model. An isotropic penetration of the cosmic rays from the upper hemisphere is assumed in the model and a spherical shape of the Earth's atmosphere is taken into account. The longitudinal effect of ionisation from cosmic rays in the mesosphere and lower thermosphere is calculated. A graphical presentation of the computational results is given for 50 and 90 km at 0 • , 40 • , 50 • and 70 • N, S latitudes and all longitudes with a step of 30 • . The results of this paper provide a basis for a quantitative understanding of the energetic processes of the middle atmosphere and mechanisms affecting the thermodynamical balance of the Earth's atmosphere.
